release: v0.2.4 - fix icon loading (proper version bump)

This is a proper version bump from v0.2.3 to v0.2.4 after discovering that
v0.2.3 was already published on Artifact Hub with a different tarball checksum.

Replace all Material-UI icon imports with Iconify equivalents to fix plugin loading.
Headlamp provides @iconify/react as a global, not @mui/icons-material.

Icon mappings:
- ErrorOutline → mdi:alert-circle-outline
- ContentCopy → mdi:content-copy
- Visibility → mdi:eye
- VisibilityOff → mdi:eye-off
- CheckCircle → mdi:check-circle
- Error → mdi:alert-circle
- Warning → mdi:alert
- Add → mdi:plus
- Delete → mdi:delete

Also fixed test-setup.ts lint errors (unused parameters).

Tarball checksum: SHA256:49062f6e9f68de49b83d53176d0bc09ce632d3df11e3397459342f51f6282131
