perf(web): keep lazy-only services and SafePipe out of main.js

The eager shell imported barrels that re-export Angular injectables and a
pipe it never uses, and their static definitions keep those modules in
main.js: PlaylistFileImportService came with PlaylistContextFacade,
normalizeDateLocale with SafePipe, and the workspace-shell-util barrel with
SettingsContextService, which #1714 grew with match counts. That growth put
master 108 bytes over the renderer.initialBytes baseline #1712 had measured
on a branch without #1714.

Add file-level entries for the three modules and use them from the eager
and settings code: renderer.initialBytes 1,626,127 -> 1,619,993 bytes.

+A baseline lowered on a branch that predates a concurrent `master` merge can
+sit below what the merged code measures: #1712 lowered it on a branch without
