Commit Message

refactor(ovs): encapsulate per-port DHCP operations within LSP lifecycle

Move per-port DHCP management from scattered controller calls into a
unified ReconcilePortDHCPOptions method on the OVS layer. This uses the
LSP's DHCP UUID pointers (compared against subnet-level UUIDs) to detect
stale per-port entries, eliminating the ListDHCPOptions cache scan and
unnecessary DeleteDHCPOptionsForPort transactions for non-DHCP pods.

Key changes:
- Add ReconcilePortDHCPOptions to LSP interface and implement it
- Embed per-port DHCP cleanup into DeleteLogicalSwitchPort
- Remove computePodPortDHCPOptions from controller
- Simplify reconcilePodDHCPOptions and reconcileAllocateSubnets
- Remove explicit DeleteDHCPOptionsForPort calls from handleDeletePod/GC

Performance: non-DHCP pod creation now has zero OVSDB transactions
(was 1x DeleteDHCPOptionsForPort); non-DHCP pod update does O(1)
GetLogicalSwitchPort + UUID comparison instead of O(N) cache scan.
