ChuckandClaude Opus 5 7e5967e160 fix(web): find installed plugins before anything has discovered them (#594)
The web process discovers plugins lazily: plugin_manifests is empty until
some endpoint calls discover_plugins(). Three routes consulted it without
discovering, so they misbehaved for as long as nothing else had run --
which, after every ledmatrix-web restart, is until someone opens the
dashboard:

- POST /display/on-demand/start answered 404 "Plugin <id> not found"
  (or "Mode <mode> not found"). Measured on a rig: 404 for over three
  minutes after a web restart, until GET /plugins/installed ran. The
  browser UI loads the plugin list first, so API-only callers (the Home
  Assistant MQTT bridge, scripts) are the ones who hit it.
- POST /plugins/toggle answered 404 "Plugin not found".
- POST /config/main did not recognise a plugin section, so it skipped
  secret separation and merged the section as-is: the plugin's API key
  was written to config.json in plain text instead of config_secrets.json.

Add _discovered_plugin_manifests(), which discovers when nothing has been
yet, and rescans once when a specific plugin id (or, for on-demand by
mode, a mode) is not found, so a plugin installed since the last scan is
found too. _installed_plugin_ids() now uses it.
