Add live routing table with CIDR mask length tracking

- Added new live_routes table with mask_length column for tracking CIDR prefix lengths
- Updated PrefixHandler to maintain live routing table with additions and deletions
- Added route expiration functionality (5 minute timeout) to in-memory routing table
- Added prefix distribution stats showing count of prefixes by mask length
- Added IPv4/IPv6 prefix distribution cards to status page
- Updated database interface with UpsertLiveRoute, DeleteLiveRoute, and GetPrefixDistribution
- Set all handler queue depths to 50000 for consistency
- Doubled DBHandler batch size to 32000 for better throughput
- Fixed withdrawal handling to delete routes when origin ASN is available
