feat(ui): i18n-translate credentials and audit_logs templates

Replace all hardcoded English text in credentials.html and audit_logs.html
with {{ _("key") }} translation function calls.

New keys added:
credentials.*: page_title, title, subtitle, total_credentials, configured,
  not_configured, legend_title, legend_db, legend_env_before, legend_env_after,
  legend_missing, legend_restart, col_credential, col_source, col_action,
  table_for, restart_title, status_missing, source_db_title, source_env_title,
  edit_in_settings, manage_settings, raw_json

audit.*: page_title, title, subtitle, siem_enabled_title, siem_off,
  siem_disabled_title, refresh_label, filter_action, filter_all_actions,
  filter_user, filter_all_users, filter_severity, filter_resource_type,
  filter_resource_placeholder, filters_section_label, col_timestamp,
  col_resource, col_ip, table_label, no_events, no_events_hint,
  pagination_label, prev_label, prev, next_label, next, critical

Reused existing keys: common.description, common.status, common.actions,
  common.edit, common.all, common.info, common.warning, common.error,
  common.refresh, common.details, common.loading
