[backport cloud/1.37] Workspaces 4 members invites (#8301)

## Summary

Backport of #8245 to cloud/1.37.

Add team workspace member management and invite system.

- Add members panel with role management (owner/admin/member) and member
removal
- Add invite system with email invites, pending invite display, and
revoke functionality
- Add invite URL loading for accepting invites
- Add subscription panel updates for member management
- Add i18n translations for member and invite features

## Conflict Resolution

- `src/components/dialog/GlobalDialog.vue`: Added missing
`DialogPassThroughOptions` import
- `src/locales/en/main.json`: Kept "nightly" section from main (was
present before PR)
- `src/platform/cloud/subscription/utils/subscriptionCheckoutUtil.ts`:
Deleted (file doesn't exist in cloud/1.37, only contains unrelated
method rename)

(cherry picked from commit 4771565486)
