fix: output flat KV format for Transifex translation extraction (#4177)

* feat: use custom formatter to output flat KV format for Transifex

Replaces --format transifex (which outputs nested objects) with a
small custom formatter that produces the flat {id: defaultMessage}
format used by all other frontend repos in openedx-translations.

* chore: remove i18n_compile script

This was part of the legacy tx CLI pull_translations workflow and is
no longer needed.

* chore: remove legacy tx CLI translation targets from Makefile

Removes push_translations, pull_translations, and
detect_changed_source_translations along with their associated
variables. These were part of the old Transifex CLI workflow which
has been superseded by openedx-translations.

* chore: remove .tx Transifex CLI config

No longer needed now that the tx CLI workflow has been removed.
