Make TURN credentials renewal time configurable via environment variable

[Copilot]

The TURN server credentials renewal interval was hardcoded to 3 hours in IceServersManager.ts. This is now configurable via the TURN_CREDENTIALS_RENEWAL_TIME environment variable.

Changes

• Added environment variable: TURN_CREDENTIALS_RENEWAL_TIME (milliseconds, defaults to 10800000 = 3 hours)
• Configuration flow: Environment variable → Zod validator → Pusher backend → Frontend configuration → IceServersManager
• Modified files:
  • play/src/pusher/enums/EnvironmentVariableValidator.ts - Added validation schema
  • play/src/pusher/enums/EnvironmentVariable.ts - Exported variable and added to FRONT_ENVIRONMENT_VARIABLES
  • play/src/common/FrontConfigurationInterface.ts - Added type definition
  • play/src/front/Enum/EnvironmentVariable.ts - Exposed to frontend
  • play/src/front/WebRtc/IceServersManager.ts - Replaced constant with environment variable
  • .env.template - Added configuration example

Usage

# .env or Docker environment
TURN_CREDENTIALS_RENEWAL_TIME=7200000  # 2 hours

The value controls how frequently TURN credentials are renewed. Default maintains existing 3-hour behavior.

Original prompt

Please turn the CREDENTIALS_RENEWAL_TIME const in play/src/front/WebRtc/IceServersManager.ts into a configurable environment variable in the play container.

@copilot Thanks. Can you simply rename the variable to TURN_CREDENTIALS_RENEWAL_TIME? (as this is really TURN specific)

Done! Renamed to TURN_CREDENTIALS_RENEWAL_TIME in commit 14359f7.
