New model.IPListEntry + jsondb CRUD, independent of any single WireGuard
server. firewall.GenerateGlobalRuleset builds an nftables table
(wireguard_ui_global) with allow/block sets evaluated at priority -10 -
before every per-server table - so it applies to all traffic on the host,
not just WireGuard. Allow entries always win over block entries.
firewall.ApplyGlobal loads it live via `nft -f`, scoped to that one table.
New "Global Firewall Lists" page (nav entry under Settings): add/delete
entries, ruleset preview, "Apply now (live)" with an explicit confirm()
warning since this affects the whole host's firewall, not just one server.

New model.FirewallRule + jsondb CRUD (GetFirewallRules/CreateFirewallRule/
UpdateFirewallRule/DeleteFirewallRule), scoped per server. firewall package
now generates a full ruleset (baseline + enabled custom rules) and can
apply it live via `nft -f` (firewall.Apply), scoped to a per-server
nftables table (wireguard_ui_<serverID>) so applying one server never
touches another server's rules or any pre-existing firewall state.
New endpoints: GET/POST /servers/:id/firewall/rules, POST .../rules/:ruleId,
POST .../rules/:ruleId/delete, POST .../apply (live, admin-only). UI in the
All Servers page: rule table with add/delete, ruleset preview, and an
"Apply now (live)" button with an explicit confirm() warning before it
touches the running firewall.
