Relevant Issues

resolves #5114

Description

Allows the document collector process to listen on a configured port using COLLECTOR_PORT, instead of always binding to 8888.

The server-side collector client already reads COLLECTOR_PORT; this change makes the collector process use the same setting, applies the same port validation on the server endpoint, and documents the variable in the server, collector, and Docker env examples.

Visuals (if applicable)

N/A

Additional Information

Invalid COLLECTOR_PORT values fall back to 8888, matching the existing default behavior.
