Map: 500-call window silently truncates incident paths, call spine and the 7d scrubber; #inc= deep links only resolve active incidents #239

Problem

LiveView.tsx:93 useCalls(500) loads the 500 newest org calls; paths, spine, ticker and scrubber are all built from it (groupCallsByIncident, LiveView.tsx:135). On a busy system that is a few hours, so a long incident's early path stops silently drop off, and an old pursuit degrades to a pin when fewer than 2 geocoded calls remain (MapView.tsx:1031).
The spine is further capped at 30 rows (WallPanels.tsx:276) with no 'N more' indicator.
The TimeScrubber '7d' preset draws a 7-day axis filled only for the loaded window, which reads as a quiet week.
LiveView.tsx:161 resolves #inc= only against activeIncidents, so a link to a pursuit that cleared five minutes ago opens to nothing.

Who asked

TOC, RCC, GSOC, HOBBY (4 of 8).

Proposal

The selected incident fetches its own calls by incident_id (bounded, paged) instead of relying on the global window.
Show 'showing latest N of M' when a spine or path is truncated.
Scrubber presets either fetch their range or visibly mark the unloaded part of the axis.
#inc= falls back to fetching the incident by id and shows it with a 'Resolved HH:MM' banner.

Data source and terms

Internal.

Effort

S/M

Acceptance criteria

An incident with 60 calls older than the 500-call window shows its full path and spine.
A deep link to a resolved incident opens it.
The 7d preset never implies zero activity for time it did not load.

PR #253 ships the spine part of this issue: "Showing latest 30 of M", a show-all-loaded toggle, and a count of calls outside the loaded window (WallPanels IncidentPanel). Still open: the per-incident call fetch, the 7d scrubber, and the #inc= fallback for resolved incidents.
