Improve accessibility for icon-only SVG buttons

[jaygaikar-09]

Summary [required]

Improved accessibility for icon-only interactive elements by adding appropriate ARIA attributes in templates/project.html and templates/index.html.

Decorative SVG icons now include aria-hidden="true" so screen readers ignore non-informative visual elements. Additionally, icon-only buttons and links now have meaningful aria-label attributes to provide accessible descriptions for assistive technologies.

These changes improve screen reader compatibility without affecting the visual UI, styling, or existing functionality.

Good accessibility-focused contribution overall. The PR correctly improves accessibility for icon-only interactive elements by adding meaningful aria-label attributes and appropriately marking decorative SVGs with aria-hidden="true".

The implementation is well scoped, avoids unrelated UI/CSS changes, and follows established accessibility best practices without affecting existing functionality or layout behavior.

I also verified that the changes are semantic-only, which keeps regression risk low while meaningfully improving screen-reader compatibility and assistive technology support.

Minor future enhancement ideas could include tooltip/focus-visible consistency for icon-only actions, but the current implementation is solid and merge-ready.

Approved for merge.
