fix(#553): eliminate hardcoded home-directory paths in Phase-6 infrastructure scripts

Migrates hardcoded ~/.timmy, ~/.config, and Path.home() references across
the autonomous infrastructure stack to use environment variables with
sensible defaults:

- scripts/autonomous_issue_creator.py:
  - DEFAULT_TOKEN_FILE → XDG_CONFIG_HOME fallback
  - DEFAULT_FAILOVER_STATUS → TIMMY_HOME fallback

- scripts/failover_monitor.py:
  - STATUS_FILE → TIMMY_HOME fallback

- scripts/dynamic_dispatch_optimizer.py:
  - STATUS_FILE, SPEC_FILE, OUTPUT_FILE → TIMMY_HOME fallback

- scripts/backlog_cleanup.py:
  - token path → XDG_CONFIG_HOME fallback

- scripts/backlog_triage.py:
  - TOKEN_PATH → XDG_CONFIG_HOME fallback

- scripts/burn_lane_issue_audit.py:
  - DEFAULT_TOKEN_PATH → XDG_CONFIG_HOME fallback

- scripts/cross-repo-qa.py:
  - GITEA_TOKEN_PATH → XDG_CONFIG_HOME fallback

This makes the Phase-6 buildings (self-healing fleet, autonomous issue
creation, community pipeline, global mesh) portable across different
user accounts and deployment environments.
