fix: map unrecognized enum values to a known "unknown" member

[Lash-L]

Enumerated state fields (speaker_state, stream_quality) previously stored any unrecognized device value verbatim (lowercased), so consumers that declare fixed options up front could receive an out-of-set value. Because _set_state_value skips None, returning None would have left a stale prior value in place, so unrecognized values are now mapped to the in-set "unknown" member instead. A stored enum value is therefore always a member of its set (or None only when the device omitted the field), and consumers no longer need to clamp the value themselves.

Summary by CodeRabbit

• Bug Fixes
  • Device settings with unexpected enum values now show as “unknown” instead of being passed through.
  • Known values continue to be handled normally, and empty or missing fields remain unset.
  • If a device later reports an invalid value for a field that previously had a valid one, the value is now replaced with “unknown”.
  • Warnings for unexpected values are still logged once per unique case.

📝 Walkthrough

Walkthrough

Adds a module-level UNKNOWN_ENUM_VALUE constant to harbor/devices/camera.py and refactors _normalize_enum_value to map unexpected, non-empty enum values to this constant with deduplicated warning logging. Updates corresponding tests to verify the new mapping behavior instead of prior passthrough behavior.

Changes

Unknown enum value handling

Layer / File(s)	Summary
Constant and normalization logic harbor/devices/camera.py	Adds UNKNOWN_ENUM_VALUE = "unknown" constant and refactors _normalize_enum_value to return this constant for unexpected non-empty enum values, with deduplicated per-field warning logging.
Test coverage for unknown enum mapping tests/test_camera_state.py	Removes the outdated passthrough test and adds tests verifying unrecognized speaker_state/stream_quality values map to "unknown", including overwriting a prior valid stored value.

Estimated code review effort: 2 (Simple) | ~10 minutes

Sequence Diagram(s)

Not applicable — the change is a localized normalization/logic refactor within a single module without multi-component interaction flows.

Poem

A rabbit hopped through fields of state,
Found values strange, mismatched, irate 🐇
"Unknown!" I cry, and log it once,
No stale old value gets a chance,
Clean enums now, my hop's elate! 🥕
