feat: allow email invites in team event assignment (#13532)

[omnialp]

Summary

This PR implements the feature requested in #13532: Allow inviting team members by email address directly from the event type assignment UI.

Changes

• CheckedTeamSelect.tsx: Added CreatableSelect support for free-form email input, email validation using emailSchema, bulk email paste support (comma/semicolon/newline/space separated), and integration with inviteMember TRPC mutation
• AddMembersWithSwitch.tsx: Added handleEmailInvite callback to process email invitations using existing team invitation infrastructure
• EventTeamAssignmentTab.tsx: Enabled email invite feature for both fixed and round-robin host assignment
• i18n: Added translation keys for invitation feedback messages

How it works

1. Users can now type or paste email addresses directly into the team member selection dropdown
2. Multiple emails can be pasted at once (comma, semicolon, newline, or space separated)
3. Invalid emails are filtered out with a toast notification
4. Already-existing team members are skipped
5. Valid emails trigger the existing inviteMember mutation to send invitations
6. Users receive toast feedback about successful/failed invitations

Technical details

• Reuses existing inviteMember TRPC mutation and backend logic
• Invites are sent with MEMBER role and WEBAPP creation source
• Uses react-select/creatable for free-form input
• Email validation via @calcom/lib/emailSchema

Fixes #13532

Hi @cubic-dev-ai

All P2 issues have been addressed:

1. Parallel processing ✅ - Replaced sequential loop with batch-based Promise.all
2. Localization ✅ - Changed hardcoded to use i18n
3. Invalid email feedback ✅ - now returns with toast notifications
4. Unbounded parallel requests ✅ - Added concurrency limit (3 concurrent requests per batch)
