Restore frontend changes omitted from merged branch

[vaheed]

What changed

• restores the global edge reconciliation action and consistent domain navigation
• restores shared dashboard, API-token, form-action, and CSS primitives that were present locally but absent from merged PR Improve and complete the Blade frontend #5
• keeps per-domain edge deployment automatic, as required by the roadmap
• restores the matching workflow coverage and manual browser qualification steps
• gives PHPUnit a bounded 256 MB test-process limit so the complete Filament/Livewire suite does not exhaust the container default

Root cause

PR #5 was merged successfully, but its final tree omitted 10 intended local changes from the earlier per-file GitHub API publishing sequence. One omitted Blade component was already referenced by two merged pages. Comparing the local worktree byte-for-byte against the merge tree exposed the gap.

Validation

• make dev-test: 142 passed, 1,151 assertions
• focused Filament tests: 19 passed, 173 assertions
• Pint: 5 affected PHP files passed
• Blade view cache: passed
• frontend asset build: passed through make dev-test
• documentation link check: 51 documents passed

Manual browser qualification was not run; it remains owner-run per AGENTS.md.
