feat(maintainer/contributors): add invite system — DB schema, send invite action, accept flow #517

[prasiddhi-105]

Summary

This PR replaces the unstructured client-side referral link mechanism (/?ref={accountLogin}) with a robust, database-tracked, email-driven structured invitation system. It introduces a complete backend management flow (send, resend, list, revoke) along with a standalone invitation landing accept page and a reactive "Pending Invites" sidebar tracking dashboard widget.

Closes #517

What was changed?

• Database Schema Modifications: Appended the invites table tracking unique tokens, timestamps, target organization installation IDs, and statuses per invited email using Drizzle ORM dialects (src/lib/db/schema.ts).
• Robust Server Actions Suite: Created four clean operations guarded by requireMaintainer() that securely manage invitations utilizing the project's native getDb() client instance (src/app/actions/maintainer/invites.ts):
  • sendInvite(): Validates input email formatting, checks for pre-existing active records, generates a secure random hex token, writes to the DB, and dispatches the email invitation hook.
  • resendInvite(): Renews an invitation by pushing the rolling expiration boundary out by another 7 days.
  • listPendingInvites(): Filters and fetches active, non-expired invitation rows for the given repository workspace.
  • revokeInvite(): Purges an active record from database indices cleanly.
• Email Template Extension: Built a dedicated HTML/text transitional email template function (sendInviteEmail) wrapping the initialized resend client package (src/lib/email.ts).
• Standalone Acceptance Router Page: Initialized src/app/invite/[token]/page.tsx as a separate, distraction-free screen outside the core dashboard shell layout. It evaluates the valid parameters, handles authentication redirection parameters cleanly via ?next=, processes multi-table records atomically inside a Drizzle .transaction(), and updates the contributor access list safely.
• Client UI Integration: Re-engineered src/app/(app)/maintainer/invite-contributor-button.tsx to handle true form submission dispatches and appended a beautiful Pending Invites sidebar tracker grid list to view statuses, resend, or revoke actions instantly.

Screenshots

Will add screenshots upon deployment to the staging environment due to a local dev auth loop. Tested via static type checking.
