get port as param or env

[Idokah]

in managed-adapter PR this line:
const port = process.env.PORT || options?.port || 8080
will become
const port = options?.port || 8080

the process.env.PORT will be passed from main.ts and the relevant tests will pass the options object with the port,
didn't want to implement it in this PR to avoid too many conflicts, will implement it in managed-adapter

Can we merge this?
