v1.0.49: fix version auto-refresh by polling from the property inspector

The v1.0.47/48 attempt pushed sendProjectsToPI() from the plugin right
after streamDeck.connect() on startup, assuming that would reach an
already-open panel post-update-restart. It doesn't: per the SDK,
sendToPropertyInspector only delivers 'when the property inspector is
visible for an action provided by this plugin', and that visibility
state is tracked per-process via live didAppear/onSendToPlugin events
-- a freshly restarted process has never received one, so the push was
silently dropped. Confirmed in testing: the panel stayed frozen on
'Updating to vX...' indefinitely.

Removed the ineffective push. Instead, the property inspector's
'Check for Updates' handler now schedules a few refreshProjects
requests (1.5s/3.5s/6s/9s after the click) -- the same proven
PI-initiated round trip already used when entering an API token, which
reliably re-populates the panel including the version text once the
new process comes back up.

Also hardened checkForUpdates(): the final 'Updated to vX --
restarting...' status is now awaited with a short delay before
process.exit(0), best-effort only, since the panel no longer depends
on it arriving.
