* fix(launcher): resume flaky downloads, drop redundant percent, fit dialogs
The binary upgrade/download flow had three rough edges:
- The status label printed "Downloading... N%" right next to a progress
bar already showing the percent. Replace it with a human-readable byte
readout ("Downloading... 12.3 MB / 45.6 MB").
- A failed download (GitHub releases are flaky) had no recourse and always
restarted from byte 0. Stream to "<dest>.part" and resume via a
"Range: bytes=N-" request (handling 206/200/416), renaming to the final
path only after checksum verification; on checksum failure the file is
discarded so the next attempt starts clean. Add a Retry button that
appears on failure and resumes from the partial file.
- Progress/install dialogs were hardcoded to oversized dimensions, leaving
a blank gap below "View Release Notes". Size each window to its content
with a sane minimum width.
Also unify the three near-identical download-progress popups into one
Launcher.showDownloadProgressWindow helper (and delete a dead unused copy
in ui.go) so the behaviour stays consistent across every entry point.
The progress callback now reports (downloaded, total) byte counts instead
of a single fraction. Resume/retry behaviour is covered by httptest-backed
unit tests in release_manager_test.go.

* fix(launcher): resolve latest version via redirect to dodge GitHub API 403
On a fresh Linux start with no LocalAI installed, the download failed with
"failed to fetch latest release: status 403". The cause is the unauthenticated
api.github.com rate limit (60 requests/hour, per IP): on shared/NAT/CGNAT/cloud
addresses it is exhausted almost immediately and every request 403s.
Resolve the latest version by following the github.com "releases/latest"
redirect instead, reading the tag from the final ".../releases/tag/<tag>" URL.
That endpoint is not subject to the API rate limit. Only the version is ever
consumed by callers, so the tag is sufficient. The JSON API is kept as a
fallback, now honoring GITHUB_TOKEN and reporting rate-limit 403/429 clearly
instead of an opaque status code.
Covered by an httptest-backed unit test that asserts the redirect path is used.

* fix: add retry logic and improve checksums.txt download handling
This commit addresses issue #7385 by implementing:
- Retry logic (3 attempts) for checksum file downloads
- Fallback to manually placed checksum files
- Option to proceed with installation if checksums unavailable (with warnings)
- Fixed resource leaks in download retry loop
- Added configurable HTTP client with 30s timeout
The installation will now be more resilient to network issues while
maintaining security through checksum verification when available.

* fix: check for existing checksum file before downloading
This commit addresses the review feedback from mudler on PR #7788.
The code now checks if there's already a checksum file (either manually
placed or previously downloaded) and honors that, skipping download
entirely in such case.
Changes:
- Check for existing checksum file at ~/.localai/checksums/checksums-<version>.txt first
- Check for existing downloaded checksum file at binary path
- Only attempt to download if no existing checksum file is found
- This prevents unnecessary network requests and honors user-placed checksums
