fix(profiles): a Codex switch reaches running and new sessions

Codex >= 0.164 sends every request through a shared app-server daemon that
outlives its TUIs and keeps the login it started with, so writing a new
auth.json changed nothing: open sessions and even new ones stayed on the
old (out-of-quota) account. After a switch, restart that CODEX_HOME's
daemon when one runs; open TUIs reconnect to it on their own (verified on
0.164.0 with two keys). The response says so (following), and the toast
tells the user running sessions follow.
