* fix(quota): support OpenAI business-account spend_control in codex
Business/enterprise OpenAI accounts return a usage payload with
spend_control.individual_limit instead of rate-limit windows. Keep the
existing primary/secondary/credits blocks unchanged and add a new
spend_limit window that surfaces used_percent and a "used / limit credits"
value label. additional_rate_limits is intentionally ignored.
Added a mobile MCP overlay so MCP tools can be opened and managed from the mobile UI without relying on desktop-only dropdown behavior.
Improved mobile session panel touch handling so tapping the status/session area opens the right panel reliably on phones and tablets.
Cleaned up mobile usage provider metadata by removing duplicate rows, hiding unset providers, and showing provider logos consistently.
Added eager loading for provider logos used in mobile usage views to avoid delayed or missing icons when the panel opens.
Refined the mobile update and about flows in OpenChamber settings so release/update information is easier to read on small screens.
Adjusted related layout, header, VS Code layout, command palette, and settings text/localization details needed for the mobile polish.
