Improve reuse package readability and detail performance

[yoshifuminakamura]

Summary

• clarify input binding summaries for public source, repository-local, and runtime-parameter inputs
• avoid placeholder values and empty estimation counts in reuse packets
• summarize profile evidence with linked artifact context
• avoid scanning every profile archive when rendering one result detail or reuse packet

Tests

• .venv/bin/python -m pytest result_server/tests/test_public_result_routes.py result_server/tests/test_result_padata_route.py result_server/tests/test_portal_list_templates.py result_server/tests/test_evidence_snapshot.py
• .venv/bin/python result_server/tests/run_result_server_tests.py
• manual route smoke check for result detail response time and gated packet routes
