fix(signage-manager): match schedule conflicts to the player

[MrYuion]

Schedule conflicts and the timeline did not match what the player does:

• Disabled playlists: they still counted as conflicts.
• Validity dates: checked by whole day only, and a schedule's end date did not cut blocks.
• Past conflicts: conflicts from earlier today were still reported.
• DST: times skipped by a DST change were drawn.
• Playlists without schedules: treated as takeovers.
• Zone search: searching for a display by zone name missed most zones.

Changes

• Disabled playlists: conflicts use only enabled takeover playlists.
• Validity dates: runs respect playlist and schedule validity to the minute.
• Past and running conflicts: conflicts that already ended are dropped. Runs still playing from yesterday are included.
• Single passes: they play alone ahead of timed runs on the player, so they conflict only with other single passes.
• DST: skipped clock times are not drawn.
• No schedules: playlistSchedules with no schedules gives one all-day, non-takeover schedule. It is exported once and replaces the copy in playlist-item-details.
• Labels: play-once label and all_day from one helper.
• Disabled blocks: "Disabled" in the aria label and tooltip.
• Conflict scan: touching runs are merged, and results are cached by assignment set.
• Smaller fixes: [(ngModel)], linkedSignal for the tab, and hour labels in the locale.

Testing

• Unit tests for each fix, with Sydney time pinned for DST. Each fails without its fix.
• nx test signage-manager (979) and nx build signage-manager pass.
• Local PlaceOS stack: 13/13 checks pass. These covered disabled playlists, mid-day validity, schedule end dates, past conflicts, single vs timed, zone search, tab sync, disabled labels, en-GB hours, no-schedule playlists and Sydney DST.

Merge order

Conflicts with #531 only in apps/signage-manager/USER_STORIES.md. Based on develop.

[Medium risk] Refines schedule conflict detection and timeline display logic.

The PR appears safe to merge based on the changes since the previous review.

What we checked:

• Spring-forward run ends early: No. playedRun calculates the end from elapsed play time, and the Sydney tests check both the block end and a later takeover conflict.

Summary

This PR makes the signage timeline and takeover-conflict checks follow the player’s schedule rules. It also improves schedule search and timeline labels.

• Timeline blocks respect playlist and schedule dates, skip clock times lost to daylight saving, and treat playlists without schedules as all-day normal content.
• Conflict checks use enabled playlists, ignore finished overlaps, and compare single passes separately from timed runs.
• Schedule lists search by zone name and keep their selected tab in sync with the route.
• Timeline hour labels follow the locale, and disabled blocks include “Disabled” in their text and tooltips.
