Vadym Samoilenko 2f4925353a feat(pause-insert): adaptive buffer, forward-snap, timeline drag + share link fix
Backend (Phase A):
- A1: Adaptive silence buffer — natural_gap_ms persisted per cue; renderer computes
  per-cue silence_before/silence_after instead of fixed 500ms; per-cue silence files
- A2: Forward-preferred snap — snap_pause_point prefers boundaries up to 4s ahead
  over boundaries within 1.5s behind, reducing mid-scene cuts
- A3: Min-gap validation — pause points with < 200ms gap trigger forward search
  to the next acceptable gap
- natural_gap_ms added to PausePointData model and api.ts type
- New config fields: whisper_snap_forward_window, whisper_snap_backward_window,
  ad_silence_buffer_default, ad_silence_buffer_min_after, ad_min_acceptable_gap
- Tests: test_whisper_snap.py (13 tests), test_video_renderer_buffers.py

Frontend (Phase B):
- B1: Drag pause-point markers — pointer state machine with 3px move threshold,
  clamp to min/max bounds, click-without-move still opens PausePointEditor
- B2: Drag freeze blocks — orange blocks translate with linked pause point
- B3: Time tooltip visible during drag, hidden on release
- Tests: TimelinePreview.drag.test.tsx (10 tests)

Fixes:
- Share link pointed to ai-sandbox.oliver.solutions — added app_url to Settings
  with correct optical-dev.oliver.solutions default; share_url now configurable
  via APP_URL env var
- Removed all ai-sandbox.oliver.solutions references from docker-compose,
  apache config, docs, and scripts
