fix: ESLint errors relating to accessibility (alt attribute and tableEditor components) (#48186)

## I have read the
[CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md)
file.

YES

## What kind of change does this PR introduce?

Improvements for screen readers:
- Added `alt` attributes to image components
- Added `aria-label` attributes and Tooltip to buttons

## What is the current behavior?

`aria-label`, `alt` attributes and Tooltip were missing

## What is the new behavior?

Buttons have now `aria-label` attributes and Tooltip.
Images have `alt` attributes

## Additional context

I’ve added `aria-label` attributes to the buttons in the Pagination.tsx
component, but these buttons don’t trigger any action. Shouldn’t we be
using non-interactive elements here?

No visual changes have been made.

## Summary by CodeRabbit

* **Accessibility**
* Added a tooltip to the “date options” control when the value is
nullable.
* Improved screen-reader labeling by adding an `aria-label` to the
number editor input.
* Added explicit `aria-label` text to pagination footer buttons for
loading, error, and help/estimate states (and marked the error-state
button as disabled).
* **UI**
* Updated the pagination loading-state button to rely on the button’s
built-in loading behavior instead of a custom spinner icon.
