Bug Fixes & Stability Improvements

A round of fixes across the platform to keep things running smoothly:

• Monitor comparisons measure the selected range against a previous period of the same length. Last 14 days used to be compared with the 15 days before it, which skewed changes in visibility, share of voice, and position.
• A prompt's average visibility in the prompt list fills in after its answers are scored again, instead of staying blank until the prompt's next run.
• Exported citation positions match the Citations table. They were one too high before.
• Tracked Claude, Claude Code, and OpenCode answers no longer repeat our search provider's quota errors. When web search is down, they say so in a neutral message.
• Perplexity tracking picks up answers again after Perplexity changed the address of its answer pages.
• API keys and MCP tokens follow the same access rules as the dashboard. They stop working once a canceled subscription ends, and work again when you resubscribe.
• To keep the API fast for everyone, responses over 100 KB are no longer cached, Business allows 250 requests a minute, and Enterprise allows 400 a minute and 24,000 an hour. A raised hourly quota now raises the per-minute limit with it.
• The marketing site no longer crashes when Google Translate is on.
