nat: add 6 unit tests for IP rewrite + table management
Tests cover:
- rewrite_src_ipv4: source IP changes, dst unchanged
- rewrite_dst_ipv4: destination IP changes, src unchanged
- rewrite_short_packet_returns_false: <20 bytes returns false
- rewrite_recomputes_checksum: checksum updates after rewrite
- nat_table_add_assigns_unique_ids: each rule gets unique ID
- nat_ephemeral_port_allocates_unique: ports are unique across calls
Total tests across filter module: 15 (5 table + 4 conntrack + 6 nat)
All passing.
