[ECO-2700] Clean up environment variables, fix documentation, remove unused frontend container in Docker

[xbtmatt]

Description

The Docker container for the frontend service had a ton of repeated variables that made the environment variable files look huge, so I removed it because we never use it (we disabled the frontend tests).

I left the frontend testing code in there in case we ever do want to use it again- just removed the option to run a frontend container in Docker, since it was unnecessary and made the code/configuration for Docker needlessly confusing.

I updated all the env files to have a corresponding network and sample values, so that it's easy to run very quickly.

Testing

Run through the examples manually to see if it actually works.

For local network:

# Navigate to `src/docker` and run:
pnpm run docker:prune
cd src/docker
docker compose -f compose.local.yaml --env-file example.local.env up -d

# Run the frontend for localnet
cd src/typescript
mv example.local.env .env
pnpm run dev

• Test on localnet

testnet:

# For testnet:
pnpm run docker:prune
cd src/docker
docker compose -f compose.yaml --env-file example.testnet.env up -d

# Run the frontend for testnet
cd src/typescript
cp example.testnet.env .env
pnpm run dev

• Test it for testnet
• Test it for mainnet as well

And it should work with the locally running testnet emojicoin indexer.

Minor stuff to fix.

Also, I don't personally use it but is there a reason to remove the frontend from docker compose ? Never mind, just read the PR description.
