fix(ci): post TTS intelligibility score on push, resolve PR number

GitHub was not emitting pull_request:synchronize for this branch, so the
score was never posted. Trigger on push and resolve the open PR number via
the API so the real WER table is posted regardless of which event fires.
Report-only: Galician (gl) is low-resource for the faster-whisper tiny STT.
