Pause transcription when a recording is paused

[shomix]

Previously, pausing a recording only paused the video - the live transcription engine kept running, so the app kept using the mic and CPU while "paused".

This wires transcription pause/resume into all recording paths so it stops with the recording and restarts on resume. Adds pause()/resume() to the transcription capture (whisper and web-speech), handles the case where the user pauses while the engine is still starting up, and adds debug logs around each transition.

Review Details

This incremental update addresses the two previously open concerns I reviewed: native transcription resume is now moved back behind a successful native_fullscreen_recording_resume, and the Whisper pause/resume error path no longer snaps desiredPaused back to the old engine state. I verified both of those changes and resolved the stale PR comments before posting this review.

Risk assessment: standard (medium) because this is recorder/transcription lifecycle logic in user-facing capture flows. The overall approach is still sound: the PR now pauses transcription with recording, preserves trailing Whisper finals when stopping from paused state, and keeps the desired pause state queued across in-flight transitions. The remaining issues are around edge-case ordering in the fallback/browser path and around mixing late Whisper finals from the old session with resumed speech from the new session.

Key findings:

• 🟡 MEDIUM Stopping immediately after a Web Speech pause can drop the last finalized words.
• 🟡 MEDIUM Whisper can interleave late pre-pause finals after post-resume speech on a quick pause→resume.

🧪 Browser testing: Will run after this review (PR touches UI code)

is this log intentional?

yep. Helps with debugging when stuff break
