feat(api, web): enhance port ACL handling and documentation

- Updated the `evofw-firewall.sh` script to refine the port ACL logic, ensuring the correct order of operations for deny and allow rules.
- Introduced a new structure for port ACL rows in the UI, allowing for better management of system and EvoFW rules.
- Enhanced the documentation to clarify the new port ACL behavior, including implicit drops for open ports and the distinction between EvoFW and system rules.
- Improved the handling of port ranges and source addresses in the UI, ensuring accurate representation of firewall rules.

These changes improve the functionality and clarity of port ACL management, enhancing user experience and system reliability.

Архитектура EvoFirewall

Централизованный control plane для firewall-агентов (Linux nft/ipset, MikroTik address-list).

Компоненты

Компонент	Путь	Роль
Web SPA	`apps/web`	ReUI Frame, TanStack Router/Query
API	`apps/api`	Fastify 5, JWT + agent tokens
DB	`packages/db`	Drizzle + SQLite WAL
Shared	`packages/shared`	Zod-контракты, RBAC helpers
UI	`packages/ui`	shadcn primitives `@evofw/ui`
Agents	`apps/api/src/agent-scripts`	install.sh, sync, MikroTik RSC

Потоки

Enroll — POST /v1/agent/enroll + X-EvoFW-Seed → pending agent
Approve — UI/API → status approved
Policy — GET /v1/agent/policy → deny/allow CIDRs + default_action + optional port_rules + hash (apply_version: 3) + script_sha256 (Linux; не в policy.hash)
Linux self-update — timer: GET /v1/agent/sync-script (ETag / If-None-Match) → при новой версии заменить /usr/local/sbin/evofw-firewall.sh и exec до policy
Apply — agent пишет kernel rules (L3 + L4 port ACL на nft), POST /v1/agent/apply-report + stats + optional host_firewall snapshot
Lists refresh — cron каждые 5 мин (json_url / domains / evobgp_community)

Политика

Именованные наборы правил (policy_sets); агенту назначается M:N через agent_policy_sets
Правило в наборе: action: deny | allow + ровно один источник — IP-список (list_id), CIDR или DNS-имя (hostname → A/AAAA, кэш в policy_rule_resolved)
Evaluate: правила всех назначенных enabled-наборов (sort + priority) + ip_overrides
Цепочка ядра всегда: deny → allow → default_action (accept | drop на агенте)
На Linux nft: deny → Port ACL (close drop, open accept, затем implicit drop для портов с open) → allow → default_action
Exact overlap: allow \ deny (conflicts_dropped); deny wins
Overrides, смена наборов, default_action, Port ACL и refresh DNS/lists бампят policy_generation

Auth

Portal SSO app id fw, permissions fw:*
Agent bearer token (sha256 hash в БД)
