fix(a11y): name icon-only buttons across product UI

[BillLeoutsakosvl346]

Summary

Icon-only buttons across chat, resource lists, knowledge dialogs, logs, workflow editing and previews, canvas controls, and the playground lacked accessible names. Add 65 aria-label attributes across 31 product files, covering every reported finding in the missing-button-name category.

Reuse existing tooltip and action text where available. State-dependent labels follow the existing UI state. Styles, markup structure, handlers, and visible text are unchanged; only accessible names and necessary formatting change.

This PR contains product changes only. The linter, its configuration and dependencies, and audit reports remain outside the PR.

Type of change

• Bug fix: accessibility

Testing

• External full-category audit: reported missing button names reduced from 65 to 0, with no new accessible-name analysis uncertainty.
• Final external committed-diff linter: completed successfully, 0 introduced findings.
• All 80 existing component tests passed across the affected app components and workflow renderer.
• Type checks passed for apps/sim and packages/workflow-renderer.
• Scoped Biome checks, API validation, and git diff --check passed.
• Source AST comparison verified all existing accessible names and all other syntax are unchanged, apart from formatting and the 65 added attributes.

The category result covers the statically reported findings; pre-existing analyzer limitations remain. Redundant-style and duplicate-artwork findings belong to separate categories.
