feat: implement LLDP topology discovery via SNMP 
Implements Phase 1 of network topology discovery using LLDP (Link Layer
Discovery Protocol) via SNMP, inspired by concepts from lldp2map.

New Features:
- LLDP-MIB walker for discovering network neighbors via SNMP
- Database schema for storing neighbor relationships
- Functions to discover, store, and query device neighbors
- Automatic device linking when neighbors are found in database

Components Added:
- Migration: device_neighbors table with unique constraint on
  (device_id, local_port, neighbor_name)
- Schema: Towerops.Topology.DeviceNeighbor for neighbor relationships
- Module: Towerops.Topology.Lldp for SNMP LLDP-MIB walking
- Functions: discover_lldp_neighbors/1, list_lldp_neighbors/1,
  remove_stale_lldp_neighbors/1 in Topology context

LLDP-MIB OIDs:
- 1.0.8802.1.1.2.1.3.3.0 (lldpLocSysName)
- 1.0.8802.1.1.2.1.3.7.1.4 (lldpLocPortDesc)
- 1.0.8802.1.1.2.1.4.1.1.7 (lldpRemPortId)
- 1.0.8802.1.1.2.1.4.1.1.8 (lldpRemPortDesc)
- 1.0.8802.1.1.2.1.4.1.1.9 (lldpRemSysName)
- 1.0.8802.1.1.2.1.4.2.1.3 (lldpRemManAddr)

CI Fix:
- Updated config/test.exs to use DATABASE_URL from environment in CI
- Fixes "connection refused to localhost:5432" errors in CI builds
- Falls back to localhost config for local development

Code Quality:
- Refactored LLDP module to reduce cyclomatic complexity
- Extracted helper functions to improve readability
- Used 'with' statement to reduce nesting in parse_management_address
- All Credo checks passing

Next Steps (Phase 2):
- Background worker for automated topology discovery
- Topology visualization in LiveView
- Recursive discovery from seed devices
