4grayandClaude Fable 5 eac1dfa09e fix(theme): replace no-op --mat-sys-* tokens with --app-* design tokens
The Material theme setup in apps/web/src/m3-theme.scss uses the older M3
API (mat.define-theme + mat.all-component-themes), which emits component
tokens but never emits the --mat-sys-* system tokens. As a result ~540
var(--mat-sys-*) references across the app were silent no-ops: the
declarations were invalid at computed-value time and fell back to
inherited/initial values, so many backgrounds, borders and dividers never
rendered and several text/icon colors sat at the wrong contrast.

Rather than migrate to mat.theme() (which would flip every no-op at once
with M3 azure-palette values foreign to the hand-tuned design), remap the
high-visibility usages to the existing --app-* design tokens defined for
both themes in m3-theme.scss, verified screenshot-driven in light and dark
via Electron CDP.

Changes:
- Add --app-error-color and --app-accent-color tokens (light + dark).
- Fix high-visibility surfaces: settings area, workspace shell header,
  playlist switcher, downloads, channel-details dialog, account-info,
  group/category management dialogs, sources context/filters panels,
  nav-list, and the .dark-theme app background.
- Point the Tailwind color palette at --app-* tokens instead of --mat-sys-*.
- Strip ~150 dead var(--app-x, var(--mat-sys-y)) fallbacks repo-wide (the
  fallback can never be taken).
- UI polish surfaced by the remap: suppress Material's circular icon-button
  state layer in the header (keep the rounded-rectangle hover), remove the
  orphan divider before the download button, remove the redundant right-edge
  accent bar on active rail items (the filled chip is enough), and raise the
  header/switcher control icons from the muted tier to --app-body-color so
  they no longer read as disabled.

Guard against regressions:
- tools/styles/check-mat-sys-usage.mjs fails on any new var(--mat-sys-*)
  reference; legacy usages are grandfathered in a shrink-only baseline
  (tools/styles/mat-sys-baseline.mjs). Wired into the CI Lint job and
  exposed as `pnpm run lint:styles`.

Docs:
- docs/architecture/theme-design-tokens.md documents why the tokens are
  no-ops, the --app-* mapping table, and the screenshot-driven migration
  protocol. CLAUDE.md updated with the token policy and the new lint check.

Scrollbar-related --mat-sys-* usages are intentionally left untouched here;
they belong to the separate branch claude/iptvnator-dark-scrollbar-2600aa.
