fix(audit-wave-10): aria-hidden sweep on decorative Lucide icons (#69)

Mechanical codemod added \`aria-hidden\` to 444 self-closing single-line
Lucide icon JSX elements across 267 .tsx files in:

- shared/, layout/, dashboard/
- admin/ (all sections)
- clients/, berths/, yachts/, companies/, interests/, documents/
- reminders/, reservations/, residential/, expenses/, email/

The regex targeted only the safe pattern \`<IconName className="..." />\`
(no other props, self-closing, capitalized component name). Every match
inspected is a decorative companion to visible text or sits inside a
button whose accessible name comes from \`aria-label\` / sr-only text
— the icon itself should not be announced.

Screen readers no longer double-read the icon + the adjacent label
text (e.g. "Pencil Pencil Edit" → just "Edit"). The existing
@axe-core/playwright smoke test (\`20-accessibility.spec.ts\`) continues
to pass.

Test suite stays at 1315/1315 vitest. typescript clean.

Closes task #69 (aria-hidden sweep) from the AUDIT-2026-05-12 follow-ups
backlog.
