feat: delete single analysis artefact in Perizie page

- backend/routers/analysis.py: add DELETE /analysis/{id} endpoint with
project access check and audit log
- frontend/src/lib/api.ts: add analysisApi.deleteOne()
- frontend/src/pages/ProjectDetailPage.tsx: add Trash2 button to each
AnalysisCard (red on hover), handleDeleteAnalysis() removes from local
state without full reload
- i18n: add delete_analysis key (it/en)
