perf(web): keep lazy-only services and SafePipe out of main.js (#1729)

* 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.

+Two effects make the exact counter move for reasons outside a PR's own diff.
+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
+#1714, so `master` measured 108 bytes over and every later PR failed the job
+until a follow-up moved lazy-only modules out of `main.js`. Re-run the job on
+an up-to-date branch before merging a baseline change. And the bundler's
+chunk-level identifier renaming shifts when a module enters or leaves
+`main.js`: moving one service out once renamed an imported identifier at 162
+call sites, eating about 320 of the bytes saved. Judge a small change by the
+`--stats-json` input sizes, not only by the counter.

 The job also refuses a weakened baselines file:
