Release version 1.2.1 - Critical bugfixes for v1.2.0

Fixed two critical bugs introduced in v1.2.0:

1. Admin UI table structure mismatch - CSS still had flexbox styling from
   old template structure, breaking new table layout. Updated admin.css to
   properly style table rows with standard table cell padding.

2. Frontend pricing display not showing - Template was checking global
   enable settings before display. Removed those checks so pricing shows
   if configured on product AND display setting is enabled.

Files changed:
- wc-tier-and-package-prices.php - Version bump to 1.2.1
- composer.json - Version bump to 1.2.1
- CLAUDE.md - Updated version and documented fixes
- CHANGELOG.md - Added detailed v1.2.1 entry with root cause analysis
- assets/css/admin.css - Fixed table styling (removed flexbox)
- templates/frontend/pricing-table.twig - Removed global enable checks
