fix(noctalia): stabilize Claude usage refresh

[CollieIsCute]

What

• Replace the stale AUR codexbar-cli-bin package with the maintained codexbar-cli package.
• Keep Codex on the fast OAuth usage source.
• Route Claude usage through the authenticated Claude CLI so Claude Code owns token refresh and rotation.

Why

Noctalia invokes the standalone CodexBar CLI. In explicit OAuth mode, CodexBar reads Claude Code-owned credentials but does not launch Claude to refresh an expired token. The provider therefore intermittently returns token expired even while Claude Code remains usable.

The previous AUR package is still at 0.45.2 and marked out of date; codexbar-cli currently packages the official 0.53.0 release.

• [Bug]: CodexBar can desync Claude Code's OAuth refresh token, forcing daily re-login steipete/CodexBar#1161
• Claude OAuth credentials not found. Run claude to authenticate. steipete/CodexBar#2516
• https://aur.archlinux.org/packages/codexbar-cli

Verification

• git diff --check
• Rendered the CodexBar modifier with chezmoi and confirmed codex=oauth, claude=cli.
• Ran the checksum-verified official CodexBar 0.53.0 Linux binary with the rendered config and Noctalia's exact 30-second command. Both providers returned usage without errors in 18.27 seconds.
• No local container testing was used.
