* Improved rendering and visual consistency of exported database schema
images by refining font handling during SVG and PNG export processes.
Schema diagrams now display with better visual fidelity when exported.

## Problem
When users export a large schema, the UI becomes unresponsive for a long
time.
This is because the underlying `html-to-image` library calls
`getComputedStyle` for every node.
## Solution
- Upgrade `html-to-image` to its latest version
- Use the new `includeStyleProperties` property to call
`getComputedStyle` only once
- Extract the image export logic into a new hook
## How to test
- Open
https://studio-staging-git-gildasgarcia-fe-2998-suggest-e7fb9e-supabase.vercel.app/dashboard/project/pdmusqfyrsascxykhlge/database/schemas?schema=auth
- Rearrange tables so that they are all visible
- Export the schema as png
- It should takes (~10-15secs)
- Do the same in this PR preview
https://studio-staging-gy13zepyf-supabase.vercel.app/dashboard/project/pdmusqfyrsascxykhlge/database/schemas?schema=auth
- It should takes ~3-5secs

## Summary by CodeRabbit
* **Improvements**
* Improved schema export: more reliable PNG/SVG exports that better
preserve visual styling, show progress state during downloads, and
surface success/error notifications.
* **Chores**
* Updated image-export library to a newer version for improved
compatibility and performance.
