The bottom Resume button on the chat panel was leaving users staring at
nothing for the 5-30s reconnect window: prepare-progress events are
intentionally suppressed on resume (the workspace is already there), so
the popover sat in the idle phase even while session.state was STARTING.
Synthesize a "resuming" phase from session state when no prepare events
are flowing, rendered as a spinner row in the popover with copy
"Resuming session — Reconnecting to the existing environment…". The
button icon also flips to the spinner so the toolbar advertises the
in-flight work without the user having to open the popover.
Extract the prepare-status reducer + section component into their own
file so the main popover module stays under the 600-line ESLint cap.
