fix(passwd): also reset The Lounge web-login password (#61)

passwd@ reset the IRC SASL credential (Ergo store + The Lounge saslPassword) but
NOT The Lounge's own web-login password (the bcrypt field used to sign in to
chat.<domain> itself). So a member who reset their password could connect to IRC
but got "auth failed" at chat.profullstack.com/sign-in.

set-irc-password.sh now sets all THREE chat credentials to the new password:
Ergo SASL, the Lounge saslPassword, and the Lounge web-login password via
`thelounge reset <member>` (AGENTBBS_LOUNGE_RESET_CMD, default targets the
dockerized The Lounge). The password is piped on stdin to `thelounge reset`, so
it never lands on a command line. Best-effort: a Lounge web-reset failure warns
but doesn't fail the run (Ergo SASL stays the primary IRC secret).

Bumped ircpass SetPassword's context timeout 20s→60s since the helper now also
runs a `docker exec thelounge ...` step.

Verified live on bbs.profullstack.com: the modified helper sets all three for an
existing member (web bcrypt match + saslPassword + Ergo store), and the affected
member's web login was reconciled.

 BBS/SSH login itself is unaffected — that's always the member's key.
 
+**Chat has three credentials, all set to the new password.** "Chat" spans Ergo
+(the IRC server) and The Lounge (the web client at `chat.<domain>`), which between
+them keep *three* secrets — `set-irc-password.sh` sets all three so one password
+works everywhere:
+
+1. **Ergo SASL** — the pbkdf2 hash in `/var/lib/ergo/irc-passwd` that native IRC
+   clients (irssi/HexChat) authenticate with.
+2. **The Lounge `saslPassword`** — how the *web* client logs in to Ergo on the
+   member's behalf (in the user's JSON `networks[]`).
+3. **The Lounge web-login password** — the bcrypt field used to sign in to
+   `chat.<domain>` *itself*, set via `thelounge reset <member>`
+   (`AGENTBBS_LOUNGE_RESET_CMD`). Missing this was the "I reset my password but
+   chat.profullstack.com says auth failed" bug: a member could reach IRC but not
+   the web client.
+
 **Why chat needs a helper.** The BBS process runs as the unprivileged `agentbbs`
-service user, but the Ergo password store (`/var/lib/ergo/irc-passwd`, `ergo:ergo
+service user, but the Ergo password store (`ergo:ergo 0600`) and The Lounge user

 independent: if one service is unconfigured or fails, the others still apply and
 the member sees a per-service ✓/✗ summary. A confirmation email (which never
 contains the password) is sent on success.
