X API read controls: pause, frequency, and lookback (pay-per-use X bills every read)

What problem does this solve?

X's pay-per-use API bills every read, and reads draw from the same credit balance and spend cap as posting. With multiple X accounts connected, Mixpost's background X analytics imports cost us quite a bit, with zero posts published yet. At that rate, reads alone would hit our spend cap mid-month and block publishing. There is currently no way to control or even see this read volume from inside Mixpost.

Describe the solution

Admin controls for X API usage, set globally and per X account:

1. Pause/disable X analytics and audience imports.
2. Set X import frequency (e.g., hourly / daily / weekly / manual only).
3. Limit the lookback window (e.g., only refresh metrics for posts from the last 7 days, or the last N posts).
4. Show daily X API usage (reads/writes) in the Admin Console.

Alternatives considered

• Lowering the X spend cap: stops the reads, but also blocks publishing once the cap is hit.
• Disabling the Laravel scheduler's import jobs: stops analytics for all providers, not just X.
• Disconnecting X accounts: stops the cost, but also stops X publishing.
• Patching Mixpost's code locally: lost on every update and hard to maintain.
