Invitation emails and acceptance flow now work reliably

Previously, inviting a new member to your organization could result in a silent failure, leaving the recipient without an email and the sender with no indication of what went wrong. Clicking a role option inside the invite modal could also accidentally submit the form before you were ready. And following an invitation link as a signed-out user would sometimes drop the token during the sign-in redirect, leaving the recipient on a broken or empty page after logging in.

All of these are now fixed. Org member invitations send correctly, role selection in the Invite member modal no longer triggers early submission, and invitation links survive the sign-in and sign-up redirect so new and existing users land in the right place after accepting.

One small addition alongside the fixes: when inviting external stakeholders to view a project, you can now include a personal message that will appear in the invitation email. Write your note in the Personal message field of the share dialog before sending — the recipient will see it alongside the standard invitation details.

The IPX logo on the invitation acceptance page also now renders correctly in all email clients and browsers.
