chore: standardize dev-only debug logging across all three SPAs

Router guards:
- apps/app: added DEV-gated logging matching admin pattern
  (route info, auth decisions, org selection, access granted/denied)
- apps/portal: added DEV-gated logging matching admin pattern
  (route info, auth decisions, backward-compat redirects)
- apps/admin: already had full logging (unchanged)

Ungated console statements fixed:
- admin/main.ts: error handler, plugin registration, mount errors
- admin/pages/login.vue, register.vue: catch block errors
- admin/pages/events/index.vue: fetch error logging
- admin/pages/wizard-examples: demo form submit logging
- admin/pages/faq.vue: catch block error

All console statements in Crewli-authored code are now gated behind
import.meta.env.DEV — zero console output in production builds.
Vuexy template demo files (views/demos/*) left as-is.
