Kalvin C 8b8d86c5d2 fix(desktop): integer-align custom reaction emoji (#4779)
## Summary

- remove the fractional half-pixel translation from custom reaction
emoji
- preserve the existing 28px reaction pill, 14×14 glyph box, and
`object-fit: contain`
- add real-app Playwright coverage for integer centering and non-square
intrinsic dimensions

### Related issue

None found. Follow-up to the Buzz emoji-warp investigation.

### Testing

- `cd desktop && pnpm exec playwright test
tests/e2e/custom-emoji.spec.ts --project=smoke` (15 passed)
- `cd desktop && pnpm test` (4,171 passed)
- `cd desktop && pnpm lint` (passed; two pre-existing informational
`useTemplate` diagnostics)
- `cd desktop && pnpm typecheck` (passed)
- `cd desktop && pnpm exec biome check
src/features/messages/ui/MessageReactions.tsx
tests/e2e/custom-emoji.spec.ts` (passed)

Independent review also mutation-tested the regression coverage by
restoring the half-pixel transform and confirming the new test fails. No
after screenshot is included because the patch preserves dimensions and
fixes subpixel raster alignment; the real-app test asserts the mechanism
directly.

Validated at `bc95969b21b58d83b7f94de4ad25e499e52b35fb`.
