## Summary by CodeRabbit
* **Bug Fixes**
* Improved handling of invalid Data API documentation links.
* If a requested table, view, or function can’t be found after loading,
users now see an error message and are redirected back to the main Data
API docs page.
* This helps prevent blank or broken documentation views when route
parameters are incorrect.

## Context
Main fix is to adjust the new home page + connect dialog (and connect
sheet) to render the project's custom domain if available

## Changes involved
- Created a `useProjectApiUrl` hook that will return the API URL
depending if custom domains is available, otherwise default to default
project API URL
- Refactored all the other places that were manually deriving the
project's endpoint
- Storage Explorer -> copy URL
- Edge Functions
- Integrations -> Data API + API Docs
- Auth Providers -> Callback URL
- Also updated the copy CTA for the addons page
- Instead of just "Change xxx", make it a bit more actionable
- For add ons with binary states (Custom domains, IPv4)
- If not enabled yet, "Enable xxx", otherwise "Toggle xxx"
- For PITR
- If not enabled yet, "Enable PITR", otherwise "Change recovery
duration"
- Also added "Edit custom domain" CTA if enabled

## To test

affected UI mentioned in the above section look correct
Feature / Refactor
## What is the current behavior?
Data API docs live at the `/api` route as a standalone page. Old links
point to the previous location.
## What is the new behavior?
Data API docs are moved to the integrations section with a dedicated
docs tab and settings tab. Old links are cleaned up, a mobile menu is
added for data API docs navigation, and minor code review fixes are
applied.
