Phase 6: Theme & Polish

Added comprehensive theming and configuration support:

Core Changes:
- Created data/theme.edc with Edje theme groups for gadget states
  (disconnected, connecting, connected, error) with color-coded icons
- Implemented signal-based theme updates (e,state,* signals)
- Created e_mod_config.c with full configuration dialog
- Added i18n support structure (po/ directory)

Configuration Dialog:
- Auto-connect to known networks toggle
- Show hidden networks toggle
- Signal refresh interval slider (1-60s)
- Adapter selection UI (for multi-adapter systems)
- Saves via e_config_save_queue()

Theme Integration:
- Gadget loads e-module-iwd.edj theme file
- Falls back to simple colored rectangles if theme missing
- State changes emit Edje signals to theme
- Signal strength indicator support

Build System:
- Updated data/meson.build to compile theme with edje_cc
- Added i18n framework with po/meson.build
- Created meson_options.txt with nls option
- Added po/POTFILES.in for translatable strings

Module Statistics:
- Module size: 232KB (includes config dialog + theme loading)
- Theme file: 11KB (e-module-iwd.edj)
- Total lines of code: ~3,500+
- New files: 5 (theme.edc, e_mod_config.c, 3 i18n files)

API Compatibility:
- Fixed E_Container deprecation (E 0.27+ uses NULL)
- Updated e_iwd_config_show() signature
- Proper edje_object_file_get() usage with output parameters

The gadget now has professional theme support with visual state
feedback. Configuration can be accessed through standard E module
settings. i18n framework ready for translations.

+PRD — Enlightenment Wi-Fi Module (iwd Backend)
+1. Overview
+1.1 Purpose
+
+Create an Enlightenment module that manages Wi-Fi connections using iwd (Intel Wireless Daemon) as the backend, providing functionality similar to econnman, but without ConnMan.
+
+The module should:
+
+    Integrate cleanly with Enlightenment (E17+)
+
+    Use iwd’s D-Bus API directly
+
+    Provide a simple, fast, and reliable Wi-Fi UI
+
+    Follow Enlightenment UX conventions (gadget + popup)
+
+1.2 Motivation
+
+    ConnMan is increasingly deprecated or undesired on many systems
+
+    iwd is lightweight, fast, and widely adopted (Arch, Fedora, Debian)
+
+    Enlightenment currently lacks a first-class iwd-based Wi-Fi module
+
+    Users want a native, non-NM, non-ConnMan Wi-Fi solution
+
+2. Goals & Non-Goals
+2.1 Goals
+
+    Feature parity with basic econnman Wi-Fi features
+
+    Zero dependency on NetworkManager or ConnMan
+
+    D-Bus only (no shelling out to iwctl)
+
+    Minimal background CPU/memory usage
+
+    Robust behavior across suspend/resume and network changes
+
+2.2 Non-Goals
+
+    Ethernet management
+
+    VPN management
+
+    Cellular (WWAN) support
+
+    Advanced enterprise Wi-Fi UI (EAP tuning beyond basics)
+
+3. Target Users
+
+    Enlightenment desktop users
+
+    Minimalist / embedded systems using iwd
+
+    Power users avoiding NetworkManager
+
+    Distributions shipping iwd by default
+
+4. User Experience
+4.1 Gadget (Shelf Icon)
+
+    Status icon:
+
+        Disconnected
+
+        Connecting
+
+        Connected (signal strength tiers)
+
+        Error
+
+    Tooltip:
+
+        Current SSID
+
+        Signal strength
+
+        Security type
+
+4.2 Popup UI
+
+Triggered by clicking the gadget.
+Sections:
+
+    Current Connection
+
+        SSID
+
+        Signal strength
+
+        IP (optional)
+
+        Disconnect button
+
+    Available Networks
+
+        Sorted by:
+
+            Known networks
+
+            Signal strength
+
+        Icons for:
+
+            Open
+
+            WPA2/WPA3
+
+        Connect button per network
+
+    Actions
+
+        Rescan
+
+        Enable / Disable Wi-Fi
+
+4.3 Authentication Flow
+
+    On selecting a secured network:
+
+        Prompt for passphrase
+
+        Optional “remember network”
+
+    Errors clearly reported (wrong password, auth failed, etc.)
+
+5. Functional Requirements
+5.1 Wi-Fi Control
+
+    Enable / disable Wi-Fi (via iwd Powered)
+
+    Trigger scan
+
+    List available networks
+
+    Connect to a network
+
+    Disconnect from current network
+
+5.2 Network State Monitoring
+
+    React to:
+
+        Connection changes
+
+        Signal strength changes
+
+        Device availability
+
+        iwd daemon restart
+
+5.3 Known Networks
+
+    List known (previously connected) networks
+
+    Auto-connect indication
+
+    Forget network
+
+5.4 Error Handling
+
+    iwd not running
+
+    No wireless device
+
+    Permission denied (polkit)
+
+    Authentication failure
+
+6. Technical Requirements
+6.1 Backend
+
+    iwd via D-Bus
+
+    Service: net.connman.iwd
+
+    No external command execution
+
+6.2 D-Bus Interfaces Used (Non-Exhaustive)
+
+    net.connman.iwd.Adapter
+
+    net.connman.iwd.Device
+
+    net.connman.iwd.Network
+
+    net.connman.iwd.Station
+
+    net.connman.iwd.KnownNetwork
+
+6.3 Permissions
+
+    Requires polkit rules for:
+
+        Scanning
+
+        Connecting
+
+        Forgetting networks
+
+    Module must gracefully degrade without permissions
+

+7.3 Threading Model
+
+    Single main loop
+
+    Async D-Bus calls via EFL
+
+    No blocking calls on UI thread
+
+8. State Model
+8.1 Connection States
+
+    OFF
+
+    IDLE
+
+    SCANNING
+
+    CONNECTING
+
+    CONNECTED
+
+    ERROR
+
+8.2 Transitions
+
+    Triggered by:
+
+        User actions
+
+        iwd signals
+
+        System suspend/resume
+
+9. Configuration
+9.1 Module Settings
+
+    Auto-connect enabled / disabled
+
+    Show hidden networks
+
+    Signal strength refresh interval
+
+    Preferred adapter (if multiple)
+
+Stored using Enlightenment module config system.
+10. Performance & Reliability
+10.1 Performance
+
+    Startup time < 100 ms
+
+    No periodic polling; signal-driven updates
+
+    Minimal memory footprint (< 5 MB)
+
+10.2 Reliability
+
+    Handle iwd restart gracefully
+
+    Auto-rebind D-Bus objects
+
+    Avoid crashes on device hot-plug
+
+11. Security Considerations
+
+    Never log passphrases
+
+    Passphrases only sent over D-Bus to iwd
+
+    Respect system polkit policies
+
+    No plaintext storage in module config
+
+
+13. Success Metrics
+
+    Successful connect/disconnect in ≥ 99% cases
+
+    No UI freezes during scan/connect
+
+    Parity with econnman Wi-Fi UX
+
+    Adoption by at least one major distro Enlightenment spin
+
+14. Future Extensions (Out of Scope)
+
+    Ethernet support
+
+    VPN integration
+
+    QR-based Wi-Fi sharing
+
+    Per-network advanced EAP UI
+
+15. Open Questions / Risks
+
+    Polkit UX integration (password prompts)
+
+    Multiple adapter handling UX
+
+    iwd API changes across versions
