f18a9cb106 Defer desktop media uploads until send (#4522)
## Summary

- send desktop messages immediately while media uploads continue in
background state across channel navigation
- show immediate progress above the composer and keep Jump to latest
above it
- report the real media stages as Preparing, Processing, Converting,
Uploading, and Finishing
- use Buzz's shared spinner during local media work, then switch to the
real percentage when byte transfer begins
- animate phase-label and status-suffix changes without overlap or
layout jumps
- keep cancel, progress fill, message publication, and community-reset
behavior coordinated with the background task
- use raw Tauri IPC for large browser files so renderer-side byte
serialization does not block initial feedback

## Why

Desktop previously blocked sending while attachments uploaded in the
composer. Large videos could also pause the renderer before progress
appeared, and the progress pill said Uploading while native media
processing was still underway. This makes the initial response immediate
and describes the work actually happening.

## Validation

- `cd desktop && pnpm check`
- `cd desktop && pnpm typecheck`
- `cd desktop && pnpm test` (3,931 passed)
- `cd desktop && pnpm exec vite build --mode e2e`
- `cd desktop && pnpm exec playwright test
tests/e2e/file-attachment.spec.ts --project=smoke` (11 passed)
- focused native media tests (80 passed)
- native Clippy with all targets and features
- pre-push native suite (2,107 passed, 14 ignored; 3 diagnostics passed)

Updated phase snapshots are included in the PR comments.

Split from #4512 so the desktop and mobile changes can be reviewed
independently.
