Create src/renderer/components/ui/icons.ts as the single re-export point
for every Phosphor icon the renderer touches, then rewrite the 95 files
that previously imported directly from "@phosphor-icons/react" to pull
from the relative-path-to-barrel instead. The TitleBar commit earlier
in this series already used ui/icons; this commit extends the pattern
to the rest of the renderer.
Benefits now wired in:
- one location where bundle tree-shaking can be reasoned about,
- typos like Briefcase vs BriefCase show up against a finite list,
- re-theming or swapping icon sets is a one-file edit,
- a lint rule that flags raw @phosphor-icons/react imports can be
added later without mass-rewriting call sites.
The barrel also re-exports the `Icon` type so call sites that type
icon props against the Phosphor component type work unchanged.
Test count stays at 363 passing; typecheck stays at 156 errors.
