feat: pre-fill user info in Zendesk support link (#6586)

Add user email and ID as URL parameters when opening the Contact Support
link to improve support experience. Only includes user data when logged
in.

## Summary

Enhanced the Contact Support command to automatically pre-fill user
email and ID in Zendesk support tickets, streamlining the support
request process for authenticated users.

## Changes

- **What**: 
- Added `useCurrentUser` composable to access authenticated user data in
`useCoreCommands.ts`
- Modified `Comfy.ContactSupport` command to append user email
(`tf_anonymous_requester_email` and `tf_40029135130388`) and user ID
(`tf_42515251051412`) as URL parameters when available
- Maintained backward compatibility by only adding user parameters when
user is logged in
- Preserved existing `tf_42243568391700` parameter for distribution type
(oss/ccloud)

## Review Focus

- Verify that the URL parameters are correctly appended only when user
is authenticated
- Confirm that non-authenticated users still get the base support URL
with just the distribution type parameter
- Check that both Firebase auth and API key auth users have their
information properly included

Example URLs generated when you press on help locally (it will change
automatically to ccloud on Cloud):
- **Logged out**:
`https://support.comfy.org/hc/en-us/requests/new?tf_42243568391700=oss`
- **Logged in**:
`https://support.comfy.org/hc/en-us/requests/new?tf_42243568391700=ccloud&tf_anonymous_requester_email=user@example.com&tf_40029135130388=user@example.com&tf_42515251051412=abc123xyz`
