Follow-ups deferred from PR #3095 (Sonarr episodeFileRank + seriesTitle/seriesId scoping), which shipped rank-based episode retention for Sonarr.

1. Radarr scoping parity: movieTitle / movieId

PR #3095 added seriesTitle (TEXT) and seriesId (NUMBER) as scope handles so a destructive rule can be pinned to one show in the rule builder. Radarr has no equivalent properties, so movie rules still need out-of-band scoping (tags, collections).

• Add movieTitle (TEXT) and movieId (NUMBER) to the Radarr application in rules.constants.ts with matching getter cases in radarr-getter.service.ts (read from the resolved movieResponse, same not-tracked -> null / transient -> undefined contract).
• Constants-driven only; no UI work expected (same as feat(rules): add Sonarr episodeFileRank with seriesTitle/seriesId scoping #3095).
• Note: TEXT EQUALS is case-insensitive in the comparator, so the id property is the rename-proof handle, mirroring the Sonarr pair.

2. Documentation

Add the three new Sonarr properties to the rule-property list on docs.maintainerr.info:

• Rank among on-disk episodes per show by air date (newest = 1) - pool semantics (on-disk only, specials/unaired/null-date excluded, fail-closed), and the recommended pairing with a scope rule (Series title / Series ID).
• Series title / Series ID - scoping usage and the case-insensitivity note above.

Document the Radarr pair in the same pass once (1) lands.
