feat(agora): change agora-api to construct mongo URI from host, username, password, port, and DB name env variables (AG-1592)

[hallieswan]

Description

Changes agora-api to construct the mongo URI with host, username, password, port, and DB name env variables, rather than specifying the URI directly in the env file. Future PR in agora-infra-v3 will set the environment variables to secrets allowing connection to existing DocumentDB instances, as described here.

Changelog

• Changes environment variables for agora-api
• Updates agora_version in agora-app/config to align with latest deployment tag
• Adds env variables missing from agora-app .env.example, which are used to populate agora-app config.json
• Fixes healthcheck for agora-apex -- container does not include curl, so use wget instead

Validation

1. Update apps/agora/api/.env and apps/agora/app/.env to create new environment variables specified in .env.example files
2. Stop any running containers: workspace-docker-stop.
3. Start agora stack: nx run agora-apex:serve-detach.
4. Navigate to teams page: localhost:8000/teams.
5. Confirm that teams and user images are displayed

LGTM! We can further optimize as per Thomas's suggestions in another PR if you'd like.

I followed the testing instructions, including updating the config files. I confirm that the team members are visible on the team page.
