- Add SnmpCredentialMappingExposed types with From impls to replace
  manual JSON construction (to_exposed_value)
- Rename to_daemon_value() → with_exposed_snmp() on DiscoveryType and
  DaemonDiscoveryRequest for clarity
- Fix receive_work_request handler: convert DiscoveryUpdatePayload to
  DaemonDiscoveryRequest and serialize with exposed SNMP credentials,
  so DaemonPoll daemons receive plaintext community strings
- Remove community string from SNMP session debug log

- Add FeatureLimitHit variant to BillingOperation enum
- Emit feature_limit_hit from network, seat, and host limit checks
- Add FeatureLimitHit to PostHog subscriber filter
- Extract use_case from OrgCreated metadata into PostHog identify()
  and group_identify() calls as a person/group property
- Add no-op match arm in Brevo service for new variant

The previous commit changed the return type to serde_json::Value
containing only session_id + discovery_type (DaemonDiscoveryRequest),
but the daemon deserializes the response as DiscoveryUpdatePayload
which requires daemon_id, network_id, phase, progress, etc.

Move with_exposed_snmp() to DiscoveryUpdatePayload so it serializes
the full payload and only patches the discovery_type field for SNMP
credential exposure.

The discovery completion subscriber was gated behind
DaemonMode::ServerPoll, preventing LLDP/CDP link resolution from
running for DaemonPoll daemons. Since resolve_lldp_links() is a
purely server-side database operation (no daemon contact needed),
the mode check was unnecessary.

- Add optional `enabled` parameter to `useTopologiesQuery()` to allow
  callers to conditionally disable the query
- Disable the query in CustomEdge, SubnetNode, and InterfaceNode when
  a topology context exists, preventing a redundant 401 on public routes

- Add query_ip_addr_table() to walk ipAdEntIfIndex (IP→ifIndex mapping)
- During deep scan, use ipAddrTable + ifTable to populate Interface MAC
  when ARP didn't provide one (e.g., hosts behind L3 boundaries)
- Add IfEntry fallback in find_host_by_mac for defense in depth
- Add ipAdEntIfIndex test data to snmpsim device files

…s tags

- Auto-generated discovery names now include network name ("Type — Network")
  in daemon registration, session completion, and stalled session cleanup
- Homepage discovery cards show daemon name in description and are clickable
  to navigate to the history detail modal
- History cards replace redundant Type field with Network, add phase status tag
- Discovery history detail modal is deep-linkable via URL params

Backend:
- Set host.chassis_id from SNMP sysName to enable CDP resolution
- Add MAC backfill tracing for ipAddrTable enrichment debugging
- Store raw LLDP chassis/port ID bytes with subtypes for typed parsing
- Add if_name field to IfEntry (migration + storage + API)
- Add StorableFilter::if_name for IfEntry lookup by short name
- CDP resolution: try port-level matching via cdp_port_id → if_descr/if_name
- LLDP port resolution: skip InterfaceAlias (non-unique), try if_name fallback
- Update demo data and examples for if_name field

Frontend:
- Add CollapsibleCard component, refactor AdvancedStep to use it
- Rework IfEntryConfigPanel: collapsible sections (CDP/LLDP default
  collapsed), if_name display, neighbor shown as HostDisplay +
  IfEntryDisplay cards with unresolved placeholder fallback,
  linked interface shown via InterfaceDisplay component
- Add UnresolvedPlaceholder shared component for missing references
- Add i18n keys for if_name and unresolved interface
- Regenerate types to pick up if_name field

- Daemon API client sends compile-time CARGO_PKG_VERSION via
  X-Daemon-Version header on every request
- Server auth middleware extracts the header as Option<String> on the
  Daemon variant, with daemon_version() accessor
- Old daemons that don't send the header get version: None

Split DiscoveryTypeForm into DiscoveryTypeConfigForm (type-specific
settings) and DiscoveryScheduleForm (schedule fields). Move discovery
type and run type selectors to Details tab. Remove tags from modal.

Create mode uses sequential tab navigation with Next/Back buttons
and progressive tab unlocking. Edit mode allows free tab navigation.
Tabs dynamically adapt: Configuration tab hidden for SelfReport,
Schedule tab hidden for AdHoc runs.

- IfEntry panel: use entity-colored tags with icons for IP address,
  subnet, neighbor ifEntry, and neighbor host display
- IfEntry panel: remove "Interface" from all labels, use SNMP field
  names (ifName, ifType), collapsible CDP/LLDP sections
- Interface panel: replace text header with subnet tag showing
  name and CIDR

Change default cron from daily (0 0 0 * * *) to weekly Sunday
midnight (0 0 0 * * 0) for both daemon auto-created discoveries
and UI-created discoveries.

Align all homepage card sections to use consistent gap-4 spacing
and minmax(360px,1fr) auto-fill grid. RecentDiscoveries had gap-3,
NetworkMetrics had minmax(240px), DaemonHealthPanel used fixed cols.
