Merge bitcoin/bitcoin#27477: test: add regression tests for #27468 (invalid URI segfaults)

[DashCoreAutoGuix]

Summary

Backport of Bitcoin Core PR bitcoin#27477 - adds regression tests for invalid URI handling in the REST interface.

Original Bitcoin commit: 467fa89

Changes

• Adds test cases for invalid URI handling (% symbol at end of request)
• Tests three REST endpoints: /headers/, /blockfilterheaders/basic/, and /mempool/contents.json
• Validates proper error message: "URI parsing failed, it likely contained RFC 3986 invalid characters"

Dash Adaptations

• None required - test-only change that applies cleanly to Dash
• Resolved minor conflict in test positioning while preserving Dash's expected_filter structure

Testing

• Python syntax validated
• Functional test interface_rest.py modified

Test Plan

• Run test/functional/interface_rest.py to verify new test cases pass
• Verify CI passes
