feat(docs): ask before Google Analytics sets cookies on the docs

[datlechin]

Why

docs.tablepro.app loads GA4 with no consent step. One page view sets _ga and _ga_GQYNPKSK83 on .tablepro.app, the parent domain. tablepro.app's privacy policy says Google Analytics cookies are not set until the reader allows them, so that sentence was false for anyone who had opened the docs.

Change

• GA4 stays. integrations.cookies in docs.json holds all Mintlify analytics back until local storage has tablepro:analytics-consent = granted.
• New docs/consent.js: the same question, wording and equal Allow and Decline buttons as tablepro.app, plus a "Cookie settings" control in the footer to change the answer.
• With no answer or a Decline, the docs stream cookie set before this change is removed.

Verified

Headless Chrome against mint dev: first visit and after Decline send no request to Google and set no cookie; after Allow the page reloads and GA loads. No overlap with the assistant launcher at 1280 and 390 wide, light and dark.

Not in this PR

• The docs and tablepro.app are separate origins, so a reader answers once on each.
• The web repo adds docs.tablepro.app to the privacy policy (docs(privacy): cover the documentation site web#60). Merge this one first.
• The docs "Support" link still points at a personal Gmail address, not hello@tablepro.app.
