fix(bio): add missing url_format columns + update PublicUrl tests

- Migration: url_format_override on bio_pages, bio_url_format on workspaces,
  needs_migration + migration_required_at on bio_pages (model casts existed, columns did not)
- PublicUrl tests updated for effectiveFormat() logic:
  - Pro default = SystemPath (no subdomain without explicit bio_url_format=Subdomain)
  - url_format_override on bio overrides workspace format
  - needs_migration=true → publicUrl() returns ''
