fix: harden input validation across all RPC endpoints (PENTEST-02)

Browse Source 
Manual security audit of 130+ RPC endpoints. Critical fixes:
- LND: validate pubkey (66-char hex), Bitcoin addresses, channel points,
  amount bounds, payment request format, memo length, peer address
- Package: validate_app_id on start/stop/restart/bundled-app handlers,
  validate volume host paths (must be under /var/lib/archipelago/),
  validate Docker image in bundled-app-start
- Container: validate_app_id on all 6 handlers, canonicalize manifest paths
- Network: path traversal prevention in connection request deletion
- Backup: backup ID validation in delete handler
- Webhooks: URL scheme validation, SSRF prevention for private IPs
- Security: validate app_id in secret rotation
- Interfaces: WiFi password length/null validation, strict IP/gateway/DNS
  parsing for static ethernet config

- [x] **PENTEST-01** — Run automated penetration test suite. Execute `scripts/verify-pentest-fixes.sh` and `scripts/test-security.sh`. Add new tests: SQL injection (even though no SQL -- test RPC params), command injection (test all params that touch shell), auth bypass attempts, session fixation, privilege escalation via container escape. **Acceptance**: All pen tests pass.
- [ ] **PENTEST-02** — Conduct manual security review of all RPC endpoints. Review each of the 80+ RPC endpoints in `core/archipelago/src/api/rpc/mod.rs` for: input validation, authorization checks, information disclosure, timing attacks on auth endpoints. Document findings. **Acceptance**: All endpoints reviewed; critical issues fixed.

Generate and apply AppArmor profiles for each app. **Acceptance**: All containers run with minimal privileges.
