Per-account token-failure isolation is now live on the matrix daemon, so a
bad credential entered via this form can no longer take down the agent's
whole matrix session — remove the experimental notice (+ its now-unused CSS).
Also relabel the account list 'configured accounts' -> 'provisioned accounts'
to match the v1 read path (lists accounts with a stored token; a
config-declared-but-unprovisioned account appears once provisioned through
the form). Docs + module header updated to match.
New standalone H0M3 page (/matrix-accounts.html) and tile. An agent
picker drives a list of that agent's configured matrix accounts (name,
homeserver, token-stored status) and a provision form that logs in by
password or stores an existing token.
Frontend half of the per-agent external matrix-account provisioning
work. Built against the v1 backend contract:
GET /matrix-accounts?agent=<name>
-> { accounts: [ { name, homeserver, token_present } ] }
POST /matrix-account-login (x-www-form-urlencoded, operator-auth)
fields: agent, account, homeserver, mode=password|token,
user_id?, password?, token?
-> 2xx { ok, user_id } | 4xx { error }
The token is never echoed back; secret inputs are cleared on submit.
Token-status dot reflects token-stored, not live session (a true
up/down indicator needs the daemon account registry, a follow-up). The
form carries an experimental notice pending per-account failure
isolation on the matrix daemon.
Blocked from merge on the backend endpoints and the daemon
failure-isolation fix; opening for review + to pin the UI/backend wire
contract.
