Model loading no longer polls, but its timeout was still defined as 600 iterations of a 200 ms poll interval. Replace those unused constants with the same TimeInterval budget of 120 seconds. Keep the existing explicit 120-second promise test and remove the assertion that only repeated the old formula.

Addresses SUPPORT-15 individually. All five production consumers keep the same name, type and value. No model loading, capture or timeout behavior changes.

Validation:

• Independent full two-file diff and production-caller review against fetched origin/main (8a38235e): GREEN.
• Actual focused testTranscriptedConstants: 98/98 assertions passed.
• Final committed head 34ebcf253: guarded bash check.sh had 21 PASS and one explicit safety failure (unfiltered fast suite guard exit 3), overall FAIL. Source stable and clean; machine proof archived before the verifier.
• verify-change.sh: paste into the slow synthetic target passed; launch speed skipped because Transcripted is already running. No app was quit. This does not prove a real model download or model-load timing.
• Exact-head hosted CI remains pending; this new head is outside the frozen Wave3 candidate.

The broader #2336 is unchanged. Draft pending remaining verification; no merge or release performed.
