gmcli send uses different sender display name than Gmail UI send-as identity

[raptor-bot]

Thanks for building gmcli. It is very appreciated.

I’m seeing a sender display-name mismatch between Gmail UI sends and gmcli sends from the same account.

Behavior

• Gmail UI send shows sender name as configured in “Send mail as”, e.g. John Doe
• gmcli send shows sender as a fallback/account name (e.g. username) instead of John Doe

Repro

1. In Gmail settings, set “Send mail as” display name to John Doe.
2. Send an email manually from Gmail UI to a test recipient.
   • Recipient sees sender as John Doe.
3. Send an email from the same account using:

  gmcli <account> send --to <recipient> --subject "test" --body "test"                                                                                                                                              

4. Recipient sees sender display name as fallback/account name (not John Doe).

Expected

gmcli send should use the same sender display identity as Gmail UI send-as settings (or provide a flag/config to explicitly set sender display name).
