[Bug]: Cc/Bcc fields hidden after navigating away from compose and returning, despite containing recipients

[rkofficial786]

Describe the bug

When composing an email with Cc and Bcc recipients, navigating to another route and returning to the compose window restores To, Subject, and body — but the Cc and Bcc fields are no longer visible, even though they contain recipients. This risks users unknowingly sending to hidden Bcc recipients, or assuming those recipients were removed.

Steps to reproduce

1. Open compose (New mail)
2. Click 'Cc' and 'Bcc' and add recipients to both
3. Add a To recipient and a Subject
4. Navigate to another route (e.g. Contacts)
5. Return to the compose window / draft
6. Observe: To and Subject are restored, but Cc and Bcc
   rows are not shown

Expected behavior

• If the draft contains Cc or Bcc recipients, those fields must be visible on restore — visibility should be derived from content (showCc = ccRecipients.length > 0 || userToggledCc), not stored as an independent boolean that resets on remount
  -A field containing recipients must never be hidden

Additional context

Likely cause: the Cc/Bcc visibility flags are local component state initialized to false on mount, independent of the restored draft values. Fix direction: initialize visibility from the restored draft (useState(() => draft.cc.length > 0)), or compute it instead of storing it.
