feat: bundle PII sanitization, onboarding wizard, NL source addition (#51, #52, #53)
Bundle export (#51):
- _redact_text() with 5 compiled regex patterns (IPv4, email, user=, host=, password=)
- build_bundle(sanitize=False) — per-entry redaction at export time
- sent_bundles table tracks every outgoing export (GET and POST /send)
- GET /api/sent-bundles exposes history; SentBundle model added
- BundlesView: Received/Sent tabs, sanitized badge, 5-entry preview, re-download
- IncidentsView: Sanitize PII checkbox next to Send Bundle
Onboarding wizard (#52):
- app/services/discover.py: journald/Docker/file detection (best-effort, safe in containers)
- GET /api/setup/status, /discover, POST /api/setup/write (additive, appends to existing)
- SetupWizard.vue: 3-step Detect → Select → Confirm
- Step 1 shows grouped summary (journald/file/docker counts)
- Step 2: collapsible groups with All/None section toggles
- journald + file: pre-selected; docker: collapsed, none pre-selected
- Step 3: YAML preview before write
- SourcesView: shows wizard on first run; Add Source button reuses it
NL source addition (#53):
- app/services/nl_source.py: keyword shortcut (13 well-known apps) + LLM fallback
- POST /api/setup/interpret: keyword → LLM → null (graceful fallback)
- NL field in wizard step 2; manual form shown when interpretation fails
- Added sources appear in grouped list immediately
