fix: persist downloaded node modules

[saratpoluri]

Description

Modify the docker compose file to use a volume mount for storing the downloaded node modules so it only needs network connection for the first deployment. Successive runs will not require network connection and the application can be run completely airgapped.

Fixes #870

[nitpick] The quote style change from single quotes to double quotes is inconsistent with the stated purpose of this PR (persisting node modules). This appears to be an unrelated formatting change that should either be part of a separate PR or explained in the description.
