fix(server): properly disable kademlia record storage

[VolodymyrBg]

Description

Replace the hack using zero-second TTL with proper record filtering in Kademlia configuration.

This PR addresses a TODO comment in misc/server/src/behaviour.rs where we were previously
using a workaround to disable storing records and provider records in Kademlia by setting
their TTL to zero seconds. The proper approach is to use the StoreInserts::FilterBoth
option, which is specifically designed for this purpose.

The changes:

1. Replace set_record_ttl(Some(Duration::from_secs(0))) and set_provider_record_ttl(Some(Duration::from_secs(0))) with set_record_filtering(kad::StoreInserts::FilterBoth)
2. Remove unused import time::Duration

These changes make the code cleaner and more maintainable by using the proper API rather than a workaround.

CI is still failing:
Version of 'libp2p-server' has been bumped more than once since last release v0.12.6.

0.12.7 hasn't been released no need to bump the Cargo.toml and a new changelog entry on the CHANGELOG.md only an entry with the change under the 0.12.7 release
