David Metcalfe 241bc112e8 fix(platforms): clear home channel when setup prompt left blank
Blank (or whitespace-only) answers to the home-channel prompt in the
interactive setup wizards previously left any previously saved
*_HOME_CHANNEL / *_HOME_ROOM env value in place, so operators could not
clear a stale home channel by re-running setup. Strip the prompt input
and call remove_env_value() on blank answers across the Discord, Slack,
Feishu, Matrix, Mattermost, WeCom and WhatsApp plugin setup wizards,
with per-adapter wizard tests covering set/clear/whitespace flows.

Squash of the three commits from PR #58421 (setup-wizard fix, matrix/
wecom extension, and 6-adapter test coverage) — one commit per
contributor on this salvage branch.

"""Tests for the WhatsApp plugin's interactive_setup wizard home-channel flow.
The interactive_setup wizard lazy-imports its CLI helpers from
``hermes_cli.config`` (get_env_value / save_env_value / remove_env_value) and
``hermes_cli.cli_output`` (prompt / prompt_yes_no / print_*); we patch those
source modules. Covers the home-channel clear-on-blank behavior added in
PR #58421 and extended in the follow-up.
