ci: gitea actions — ci (build/test/lint) + deploy

Стандартный набор по паттерну tasks/booking/telephony:
- .gitea/workflows/ci.yml: go build + go test + golangci-lint v2.4
  на каждый push/PR. Линтер строгий (zero-warnings policy).
- .gitea/workflows/deploy.yaml: на push в main собирается образ,
  пушится в gitea registry (cluster-local + node-local), kubectl
  применяет все k8s/* и роллит deployment с image::<github.sha>.
- .golangci.yml: тот же набор линтеров что в остальных Go-сервисах
  (errcheck/govet/ineffassign/staticcheck/unused) + exclusions
  для типичных «безопасных» свежих ошибок (Close/Encode/Rollback).

REGISTRY_USERNAME/REGISTRY_PASSWORD secrets — те же что у других
сервисов организации (нужно настроить repo-secrets в Gitea Admin
перед первым deploy'ем).
