🎨 Palette: Add type=button and aria-label to inline section controls

[aafre]

What: Added type="button" and explicit aria-label attributes to icon-only and inline control buttons across SectionEditor, ExperienceItem, and EducationItem components.
Why: Prevents accidental form submissions and ensures screen reader users can understand the purpose of icon-only controls.
Before/After: No visual changes, purely accessibility and semantic HTML improvements.
Accessibility: Improves keyboard/screen-reader accessibility by providing clear labels for 'Save', 'Cancel', and 'Remove' actions that previously only relied on emoji or tooltips.

Code Review

This pull request improves accessibility and prevents accidental form submissions by adding type="button" and aria-label attributes to control buttons in the EducationItem, ExperienceItem, and SectionEditor components. The .Jules/palette.md documentation was also updated to include these standards. Feedback was provided to make aria-label values unique for list items by incorporating their indices, which helps screen reader users distinguish between similar actions.

[gemini-code-assist]

When rendering multiple identical controls in a list, the aria-label should be unique to help screen reader users distinguish between them. Including the index or a specific identifier for the item being removed would significantly improve accessibility. Additionally, ensure the button is conditionally rendered only when the removal handler is provided, and explicitly set type='button' to prevent unintended form submissions.

Suggested change

	aria-label="Remove description point"
	type="button" aria-label={'Remove description point ' + (descIndex + 1)}

References

1. For optional UI elements like a delete button, make the corresponding handler prop optional and conditionally render the element only when the prop is provided.
2. Explicitly set type='button' on elements that are not intended to submit a form to prevent unintended form submissions.

[gemini-code-assist]

The aria-label for this button should be unique for each item in the list. Providing context, such as the item's index, ensures that screen reader users can identify which specific item they are interacting with when navigating by buttons. Additionally, ensure the button is conditionally rendered only when the removal handler is provided, and explicitly set type='button' to prevent unintended form submissions.

Suggested change

	aria-label="Remove item"
	type="button" aria-label={'Remove item ' + (itemIndex + 1)}
