fix(bio): plan-aware URL + plan-seeder + ulid→slug fix
- Migration: add bio_pages_limit to plans, make limit cols nullable (agency=unlimited)
- PlanSeeder: 4 plans (free/pro/business/agency) with tier/features/bio_pages_limit
- workspaces:assign-default-plan command: assigns free plan to unassigned workspaces
- BioPage::publicUrl(): free=apex-path, pro+=subdomain, custom=custom-domain
- Security: str_ends_with check uses '.'.$apex to prevent evilnimu.li bypass
- BioPage::shortPublicUrl(): URL without scheme for display
- PlanLimitsService: use bio_pages_limit column (was features['bio_pages']), null=unlimited
- BioPageController: fix $bio → $page variable (view expects $page)
- Bio index/edit views: use publicUrl()/shortPublicUrl(), not hardcoded ULID URLs
- Bio edit view: publicUrlBase/displayUrlBase from component (plan-aware prefix)
- Create-bio modal: plan-aware URL prefix display
- PlanFactory/WorkspaceFactory: free()/pro() states for tests
- Tests: PublicUrlTest (5 cases), Free404FixTest (3 cases)
Known pre-existing failure (not caused by this change):
- Tests\Feature\Auth\EmailVerificationTest::email can be verified
