feat: restore previous session connections and add start-maximized option

No description provided.

What

• Session restore: on startup, reopen all connections that were open when the
  app was last closed, reactivating the last active one. Toggle in
  Settings → General → Startup ("Reopen Last Connections").
• Start maximized: optional setting to open the window maximized on launch
  ("Start Maximized").

How

• Backend persists last_open_connection_ids + last_active_connection_id and a
  start_maximized flag in config.json; the window is maximized in the Tauri
  setup hook.
• Frontend persists the open-connection set and auto-connects on the Connections
  page, switching to the last active connection.

i18n

• Added autoConnectLastConnection, startMaximized (+ descriptions) across all
  8 locales.

WARNING: autoConnectAttempted is set before checking the autoConnectLastConnection setting

If the user disables auto-connect (or it starts disabled), the flag is set to true anyway. If they later enable the setting in the same app session, the effect re-runs but is blocked by the already-set flag, so auto-connect never executes.

Move autoConnectAttempted = true; to after the settings.autoConnectLastConnection === false check.

WARNING

File	Line	Issue
src/pages/Connections.tsx	103	autoConnectAttempted set before settings check, preventing auto-connect from working if the user toggles the setting on after it was initially off

Other Observations (not in diff)

• src/contexts/DatabaseProvider.tsx (lines 779–790): The persistence effects intentionally skip null/empty states to avoid a startup race condition. This is a documented trade-off, but it also means intentionally closed connections are not cleared from the saved state.
