🤖 fix: make Review tab toggles global instead of per-workspace (#491)

The 'Show Read' and 'Uncommitted' toggles in the Review tab were stored
per-workspace, requiring users to configure them separately for each
workspace. This changes them to global settings that apply across all
workspaces.

**Changes:**
- Storage key `review-include-uncommitted:${workspaceId}` →
`review-include-uncommitted`
- Storage key `review-show-read:${workspaceId}` → `review-show-read`

Users' preferences for these toggles will now persist when switching
between workspaces.
