fix: wait for fonts and retry fit until proper dimensions

- Wait for document.fonts.ready before fitting (ensures correct cell metrics)
- Retry fit every 100ms if rows <= 1 or cols <= 10 (layout still settling)
- Up to 30 retries (3 seconds) for layout to stabilize
- Remove redundant delayed fits, keep only header auto-hide fit at 4s
