Add backend invitation-link env configuration (FRONTEND_BASE_URL, INVITATION_TOKEN_SECRET)

[Copilot]

Backend invitation-link configuration was incomplete: the service did not declare dedicated runtime settings for frontend link base URL and invitation token signing secret. This PR adds those config surfaces and documents expected production values (including https://taskflow.mukund.xyz for this deployment).

• Runtime env wiring (backend compose)

  • Added FRONTEND_BASE_URL and INVITATION_TOKEN_SECRET to backend API service env in:
    • Backend/docker-compose.yml
    • Backend/docker-compose.azure.yml
  • Local compose defaults frontend base URL to http://localhost:3000; Azure compose requires explicit values.

• Environment documentation

  • Updated README.md backend env sections to include:
    • FRONTEND_BASE_URL
    • INVITATION_TOKEN_SECRET
  • Clarified production guidance for this repo deployment domain (https://taskflow.mukund.xyz).

Example config shape introduced:

environment:
  FRONTEND_BASE_URL: ${FRONTEND_BASE_URL}
  INVITATION_TOKEN_SECRET: ${INVITATION_TOKEN_SECRET}
