Fixes: https://github.com/go-gitea/gitea/issues/21045 - Move heatmap data loading from synchronous server-side rendering to async client-side fetch via dedicated JSON endpoints - Dashboard and user profile pages no longer block on the expensive heatmap DB query during HTML generation - Use compact `[[timestamp,count]]` JSON format instead of `[{"timestamp":N,"contributions":N}]` to reduce payload size - Public API (`/api/v1/users/{username}/heatmap`) remains unchanged - Heatmap rendering is unchanged, still shows a spinner as before, which will now spin a litte bit longer.
