feat(commands): /pause /resume + adaptive dispatch + richer /status

Add two new Telegram commands so the user can manage monitoring without
restarting the process:

- /pause sets lifecycle.user_paused = True. The detection loop then
  short-circuits via _should_skip without touching FSM / canary state.
- /resume clears user_paused. R2 decision: drift-pause is NOT lifted by
  plain /resume (the drift may be legit and require recalibration).
  "/resume force" (value=1) also calls canary.resume(). The response
  message adapts to context:
    - drift active + plain resume → explains force requirement
    - force + drift → confirms override, warns about recurrence
    - out-of-window → explains monitor will resume at next open
    - otherwise → plain "Monitorizare reluată"
- /status now shows "Activ: <pause_reason | activ>" and window state.

commands.py: extend CommandAction literal and _parse_command to accept
pause, resume, and "resume force" (value=1 signal).

Tests: test_commands.py parse coverage;
test_pause_command_sets_user_paused_and_skips_detection,
test_resume_clears_user_paused_and_canary_when_forced,
test_resume_during_drift_keeps_canary_paused_without_force (R2 #21),
test_resume_out_of_window_responds_with_pending_message,
test_status_command_reports_pause_reason,
test_lifecycle_with_drift_then_resume_then_fire (E2E #16).
