tests: functional tests for P2P peer eviction logic

[naftalimurgor]

Motivation

Summary

• Bitgesell inherits P2P inbound eviction logic from Bitcoin Core (introduced around 2020).
• Currently, there is no functional test coverage for this feature in the Bitgesell codebase.
• Bitcoin Core added a dedicated test in PR [#16756](test: Connection eviction logic tests bitcoin/bitcoin#16756) to simulate and verify eviction behavior.
• The test ensures:
  • Peers relaying recent blocks or transactions are protected.
  • Peers with low ping are less likely to be evicted.
  • Eviction activates correctly when inbound limit is exceeded.
• Porting this test to Bitgesell would:
  • Improve test coverage for P2P networking.
  • Help identify future regressions in eviction logic.
  • Contribute toward testing-related bounty opportunities.

Proposed Action:

• Adapt Bitcoin Core's functional test (test_inbound_evict.py) for Bitgesell.
• Ensure it runs within Bitgesell’s test framework or create necessary scaffolding if absent.
