fix: refactor cache-checkout to use actions/cache@v4 with fallback (#26702)

This fixes cache propagation delay issues with Blacksmith's distributed cache.

The previous implementation used separate save/restore actions with
fail-on-cache-miss: true, which failed when the cache wasn't immediately
available after being saved by the Prepare job.

The new implementation uses actions/cache@v4 (combined save/restore)
with a fallback to do the checkout if cache miss, matching the pattern
used by cache-build and cache-db which don't have this issue.

Changes:
- Refactored cache-checkout action to use actions/cache@v4
- Added fallback checkout step when cache miss occurs
- Removed mode input (no longer needed)
- Updated all workflows to use the simplified cache-checkout action
