fix: Use search API instead of filter in the filter in the endpoints (#13651)

- Replace `POST /contacts/filter` with `GET /contacts/search` for
contact lookup in compose new conversation
- Remove client-side input-type detection logic (`generateContactQuery`,
key filtering by email/phone/name) — the search API handles matching
across name, email, phone_number, and identifier server-side via a
single `ILIKE` query
- Filter the contacts with emails in cc and bcc fields.
