Interface deduplication in create_with_children queried by (host_id,
subnet_id, ip_address) but lacked MAC address fallback. When subnet_id
changed between discovery runs, existing interfaces weren't found,
causing duplicates that cascaded to port/service conflicts.

Changes:
- Add SqlValue::MacAddress variant for query binding
- Add EntityFilter::mac_address() filter method
- Add MAC fallback query after subnet+IP query fails
- Add partial index on (host_id, mac_address) for efficient lookups

The fix aligns interface deduplication with Interface::PartialEq which
already supports MAC matching.

- Add ASCII banner matching daemon style
- Add LOG_TARGET constant for consistent log filtering
- Log initialization milestones (database, services, routes, scheduler)
- Add configuration summary (port, URL, deployment type, features)
- Add "Server ready" message with API/UI endpoints
- Add shutdown logging on Ctrl+C

Backend:
- Add PaginationParams struct with limit/offset query parameters
- Add PaginationMeta to API responses (total_count, limit, offset, has_more)
- Create custom Query extractor using serde_qs for bracket notation support
- Implement get_paginated() in storage layer with COUNT query
- Update all handlers to return paginated responses
- Default limit: 50, max: 1000, use limit=0 for unlimited

Frontend:
- Regenerate TypeScript types with PaginationParams/PaginationMeta
- Update all queries to pass limit=0 (maintains current full-load behavior)
- DataControls already has client-side pagination (20 items/page)

API usage:
  GET /api/v1/hosts?pagination[limit]=10&pagination[offset]=20

Move tag storage from per-entity UUID arrays to a centralized
entity_tags junction table, enabling cleaner bulk and inline
tag operations across all entity types.

Backend:
- Add entity_tags junction table with migration
- Create EntityTagStorage and EntityTagService for tag CRUD
- Add Taggable trait implemented for all 9 entity types
- Add generic /entity-tags endpoints (add, remove, bulk)
- Update handlers to hydrate tags from junction table
- Update StorableEntity impls to skip legacy tags column
- Clean up junction table entries on entity deletion
- Drop legacy tags columns and cascade trigger

Frontend:
- Add tag mutations (useAddEntityTag, useRemoveEntityTag, useBulkAssignTags)
- Create TagPickerInline component with entity mode
- Add bulk tagging support to DataControls
- Update all cards with inline tag editing
- Update all tabs with bulk tagging props
