Factory/Droid: Remove outdated Premium meter — billing is now unified Standard tokens

[hhh2210]

Summary

Factory (Droid) has unified its billing model to a single Standard tokens pool that applies to all models. The Factory billing page at app.factory.ai/settings/billing now explicitly states: Standard tokens now apply to all models.

The current CodexBar implementation displays two separate meters — Standard and Premium — but the Premium meter is always at 100% (unused) since premium tokens no longer exist as a separate billing concept.

Current behavior

CodexBar shows two rows for Factory/Droid:

• Standard: shows actual token usage (e.g. 41% left)
• Premium: always shows 100% left (never consumed)

This is because FactoryUsageData still parses both standard and premium fields from the API response, and the descriptor maps them to sessionLabel: Standard / weeklyLabel: Premium.

Expected behavior

Since Factory now uses a single unified token pool, CodexBar should either:

1. Hide the Premium row entirely when premium usage is zero / premium allowance matches standard
2. Or show a single combined Tokens meter

• FactoryProviderDescriptor.swift: lines 13-14 define the Standard/Premium labels
• FactoryStatusProbe.swift: FactoryUsageData (line 181-186) parses both fields

Environment

• CodexBar version: latest (installed via Homebrew)
• Factory plan: Pro Annual
