[IOTDB-14788][Docker] Add REST API port to Docker Compose example

[ShauryaChauhan1411]

Fixes #14788

Description
Added port 18080 and enable_rest_service=true to the Docker Compose standalone configuration to allow REST API access by default.

Note
I searched for the Rest-Service.md documentation files but they do not appear to be present in the root of the current master branch.

Hi @CritasWang, @HTHou. It seems the Cluster IT / Simple (17) check failed due to a SUBSTRING function error and type validation issues. Since my changes are strictly limited to the docker-compose-standalone.yml file, these failures appear to be unrelated to my PR.

Could you please trigger a re-run of the failing checks?

[ShauryaChauhan1411]

Hi @CritasWang @HTHou Gentle follow-up on this PR.

I noticed the Cluster IT - 1C3D / Simple (17) check is failing, but after checking the logs, it seems to be a SUBSTRING function error which appears unrelated to my changes in docker-compose-standalone.yml.

Could you please trigger a re-run of the failing checks? If they still fail, I'd be happy to help investigate if it's a flaky test in the current master branch. Thanks!

hi @ShauryaChauhan1411, I think the default configuration of docker should be same as the distribution package, so I think it will be better not to change that

And BTW, if you want to change the default conf for some envs, it's better for you to firstly have a discussion in the dev mail list.

Thanks for the feedback, @JackieTien97 . I see your point about maintaining consistency with the distribution package. I'll revert the default port changes in this PR to match the standard config. I'll also start a thread on the dev mailing list to see if the community thinks there's a better way to handle REST API visibility for Docker users without breaking that consistency.

Hi @JackieTien97 , I've reverted the changes in docker-compose-standalone.yml to match the distribution package defaults.

Regarding the REST API visibility for specific environments, I'll follow your advice and start a discussion thread on the dev mailing list to see how the community prefers to handle this. Thanks for the guidance!
