fix: centralize URLs, tighten models, and polish SwiftUI bindingsv3.1.3

- Add shared HutchDeepLinkURL constants for app, widgets, and tests.
- Bump marketing version to 3.1.2 and build to 70 (app + widget extension).
- Point Hutch stats default base URL at HutchStatsAPI; add SRHTWebURL status
  incident feed and reuse it from SystemStatusService.
- Group Project into Metadata and Resources; split ContributionStatsResponse
  into StatsWindow and StatsTotals with updated decoding and tests.
- Replace @Bindable usage with explicit Bindings in Profile, Projects list,
  and repository ACL flows; simplify Home pinned-item helper; add no-op
  bodies on cancel alert buttons where the compiler requires a statement.
- Move repository row build-status indicator next to the relative-updated
  caption and reserve a fixed 8×8 slot so the row does not jump when status
  loads.
- Use NSString.lastPathComponent for build artifact filenames; collapse
  duplicate ACL error branches; minor HutchStats HTTP and XMLParserDelegate
  cleanups.
- Point widgets at HutchDeepLinkURL helpers; align tests with the new
  response and URL types.
