[hozzjss]

Chore - Add polling env var

1. Description

some operations like the deposit and reclaim take time to complete and the data need to be polled to get the current status of the operation, however currently in deposit and reclaim the polling interval in milliseconds is hardcoded which means that to change them we'll need to commit changes and rebuild the image

3. Execution Checklist

• Add env var in .env.sample for all polling operations
• Read the env var and pass to the bridge config aciton
• Add the polling ms variable to the deposit and reclaim status hooks
