feat(firewall): nftables hit-counter pro Regel + Live-Hits-Spalte in der UI

Browse Source 
- ruleset.nft.tpl: operator-rules bekommen `counter <action> comment "egid:<id>"`
  → nft zählt Packets + Bytes per Regel ab dem letzten Ruleset-Apply
- handlers/firewall_counters.go: GET /firewall/counters parst
  `sudo nft list table inet edgeguard` per Regex, liefert [{rule_id,packets,bytes}]
- handlers/firewall_counters_test.go: unit-tests für parseNFTCounters
- Firewall/Rules.tsx: neue "Hits"-Spalte (Packet-Count, Tooltip mit Bytes),
  10s-Polling via TanStack Query ['fw','counters']
- i18n de+en: fw.rule.hits
