Clears template cache on save to fix stale cached templates (NB-1574)

When email templates are updated via the UI, the changes now take effect
immediately for subsequent emails. This fix addresses cache invalidation
by clearing three cache layers:

1. Laravel application cache (existing)
2. Compiled Blade view cache (new)
3. PHP OPcache for precompiled files (new)

The issue occurred because even though the template data cache was cleared,
Laravel's compiled Blade views and PHP OPcache retained the old content.

Changes:
- Added Artisan::call('view:clear') to clear compiled Blade views
- Added opcache_reset() to clear PHP OPcache when available
- Added comprehensive regression test to verify cache invalidation

Test results:
- Manual testing via tinker confirms cache is cleared on update
- Updated templates are immediately available for email generation
- No stale content is served after template edits
