fix(invites): redirect to invited space, improve invite emails

- Fix invite accept fetch URL in shell.ts (was missing /api/spaces prefix)
- After accepting invite, redirect to the invited space instead of reloading
- Notification actionUrls now point to the space subdomain (https://slug.rspace.online)
- Direct-add email includes inviter name, role, and space description
- Identity invite email includes space name/role context when inviting to a space
