The member-facing infrastructure page no longer documents who holds room power
or which automation accounts exist. Record it here instead: @inference-admin as
administrator of record, the retired @inference-bot account and its two
un-leavable rooms, and the @ops_audit review account.
Also repairs a heading glitch carried over from the docs page: a line began with
a bare '#infrastructure', which Markdown parsed as an <h1>. The room names are
now written inline so no line starts with '#'.
