fix: re-hide macos dock icon after parentless dialogs

[afonsojramos]

Summary

Since v7.0.0 the macOS dock icon occasionally reappears even though Gitify runs as a dock-hidden (accessory) app, and only a restart re-hides it.

Investigation

Tested live on macOS by driving the real built app (hidden window, setVisibleOnAllWorkspaces, accessory policy) and measuring app.dock.isVisible():

• Reproduced: app.dock.hide() can be silently dropped when it races an app activation transition. In the experiment, hide() called 500ms after the dock became visible left the icon showing; a later hide() succeeded. electron-menubar calls dock.hide() very early in startup, so a lost race there leaves the icon stuck for the whole session. A restart re-rolls the race, which matches "occasionally showing" + "restart restores it".
• Not reproduced (on this machine/OS): the parentless dialogs (updater "restart to install", first-run prompt) did not flip the dock. Kept the dialog-path re-hides anyway as cheap defense, since dialog-driven activation is version-dependent macOS behavior.
• DevTools (detached) also did not affect the dock.

Fix

1. Startup re-assert — moved into electron-menubar per review feedback, since the library owns the showDockIcon: false contract: fix: re-assert hidden dock after startup hide race electron-menubar#123, released as 10.1.4. This PR bumps the dependency and drops the app-level copy.
2. Dialog-close re-hides (app-level, defensive): re-assert hidden after the updater dialog is dismissed and after the first-run prompt closes.

Tests

• updater.test.ts: dismissing the update dialog re-hides the dock.
• first-run.test.ts: the dock is re-hidden after the prompt closes.
• Library-side coverage for the startup race lives in electron-menubar#123.

Full suite passes (1198 tests), pnpm check and tsc --noEmit clean.

Closes #3069

should this logic be within electron-menubar based on this config param being set?
