feat(jira): add editable jira_email field per user

Users can now set a separate Atlassian email for Jira authentication
in Settings → Profile → Jira Integration. Falls back to the Aegis
account email when not set, so existing setups are unaffected.

- Migration b043: adds jira_email column to users table
- User model/schema: expose jira_email read/write
- jira_service: _effective_jira_email() uses jira_email ?? email
- Frontend: replaces read-only email display with editable input

 Authentication model
 --------------------
-Each Aegis user authenticates to Jira with their own corporate email
-(``user.email``) and their personal Atlassian API token
-(``user.jira_api_token``).  This way every Jira action is traceable to a
-real person rather than a shared service account.
+Each Aegis user authenticates to Jira with their own Atlassian email and
+personal API token.  The email used is ``user.jira_email`` when set, falling
+back to ``user.email`` (the Aegis account email).  This lets users specify a
+separate corporate Atlassian email without changing their Aegis login.
+The token is stored in ``user.jira_api_token``.
