improvement(ui): use shared sizing for auth controls

[BillLeoutsakosvl346]

Auth, invite, unsubscribe and public-file controls now use shared Chip/ChipInput size="lg" and align="center". Retires the height/alignment constants and moves the SSO email link to ChipLink. Labels, URLs, validation, reveal behavior, loading/disabled states and handlers remain unchanged.

Intentional differences: 34→36px fields; SSO email action 32→36px height, 12→14px text and 10→8px corners with the shared outline treatment. Existing 36px auth actions retain their geometry.

All workspace type checks, import/API audits, lint and the complete EMCN suite pass; all 44 relevant consumer tests pass. Browser fixtures cover light/dark, error/reveal, focus/hover, disabled/loading, 390px embedded document viewports and enlarged text. Backend auth/invite/unsubscribe/provider/Slack services were not exercised. No linter or review artifacts are included.

Both external linters ran against the actual target: 17 targeted findings removed (732 → 715 total), no new full-scan findings, and zero diff-checker violations.

The PR appears safe to merge; the shared component APIs preserve the intended geometry and existing interaction behavior.

Summary

This PR consolidates auth-adjacent control geometry onto the shared EMCN sizing and alignment APIs.

• Replaces local height and descendant-flex overrides with size='lg' and align='center'.
• Removes the now-unused auth sizing constants.
• Standardizes password, email, public-file, invite, unsubscribe, OAuth consent, and Slack setup fields.
• Replaces the nested SSO email Link/Button composition with the canonical ChipLink while preserving callback handling.
• Updates the SSO test mocks for the shared component APIs.

Before → after visual checks for 4c26fc6. Actual password/submit wrappers plus equivalent social, invitation, SSO and secret controls, with local handlers. Backend authentication/invitation/unsubscribe/provider/Slack services were not exercised.

Most auth controls retain 36px geometry. Public fields grow 34→36px. The SSO email link adopts 36px height, 14px text, 8px corners and shared outline styling.
