Bob.Hou ff320cbfd5 fix(combo): exempt content_filter from empty-content detection (#7973) ...

## Problem

When Gemini Flash returns a safety-filtered response (finish_reason:
content_filter, empty content), isEmptyContentResponse() misclassifies
it as a fake-success empty response and returns HTTP 502.  This triggers
the combo fallback chain and account cooldown escalation (5s → 10s →
20s → 40s), even though the response is a legitimate terminal state.

## Root cause

errorClassifier.ts line 14: LEGIT_EMPTY_OPENAI_FINISH only exempts
"length" and "tool_calls".  The "content_filter" finish reason
(mapped from Gemini's SAFETY/PROHIBITED_CONTENT) is not exempted,
so safety-filtered responses are treated as empty content failures.

## Fix

Add "content_filter" to LEGIT_EMPTY_OPENAI_FINISH so safety-filtered
responses pass through as valid (though filtered) completions.

## Testing

- 10/10 unit tests pass (empty-content-stopreason-3572.test.ts)
  including 2 new content_filter test cases
- E2E: hot-patched OmniRoute v3.8.48 on X500, verified the previously
  failing prompt (4.6KB review) now returns valid content instead of
  empty-content 502
