Split api/openapi.yaml schemas into api/schemas.yaml so structs can be
generated independently from the API server code. Models now generate
into internal/model/ via oapi-codegen, with the server referencing them
through import-mapping. Moved PtrTo helper to internal/utils and removed
storage.ReportSummary in favor of model.TestSummary.
CalculateScore now accepts a forWhitelist flag to handle whitelist
scoring logic separately. The final blacklist grade combines both
RBL and DNSWL results using MinGrade for a more accurate reputation
assessment.
Embed rspamd-symbols.json in the binary to provide human-readable
descriptions for rspamd symbols in reports. Optionally fetch fresh
symbols from a configurable rspamd API URL (--rspamd-api-url flag),
falling back to the embedded list on error. Update the frontend to
display descriptions alongside symbol names and scores.
Remove authResults parameter from AnalyzeDNS, making it independent of
the authentication analysis step. Instead, parse DKIM-Signature headers
directly to extract domain and selector.
