v2.1.2 - inCinemas Coming Soon fallback

What's changed

• Radarr Coming Soon eligibility now also accepts inCinemas as a
  release-date fallback alongside digitalRelease and physicalRelease
  (closes #87, PR #88).
• When more than one of inCinemas, digitalRelease, and
  physicalRelease is populated, the earliest qualifying date inside
  the configured look-ahead window is selected, so the displayed
  countdown and releaseLabel reflect the soonest real release.
• Already-imported movies are still excluded via hasFile === false, and
  monitored filtering is unchanged — theatrical-only entries that have
  already been downloaded will not reappear in Coming Soon.
• The configurable look-ahead window (coming_soon_lookahead_days,
  default 90) is fully respected: dates outside the window are
  ignored when picking the earliest eligible release date.

Tests

• cd server && node --test test/ — 142 passed, 0 failed, including
  existing coverage for digitalRelease/physicalRelease selection,
  earliest-of-eligible logic, look-ahead clamping, the hasFile filter,
  and monitored filtering.
