Major code cleanup and deduplication

REMOVED:
- DOCS.md (redundant with README.md)
- QUICKSTART.md (content integrated into README)
- entrypoint.sh (redundant with run.sh)

ADDED:
- scripts/common.sh - Common utilities library
  - Consolidates logging fallbacks (9 files affected)
  - Unifies script directory detection (7 files affected)
  - Standardizes directory/file validation
  - Provides error handling patterns

IMPROVED:
- Fixed version mismatches (dashboard API 1.1.0 → 1.2.0)
- Standardized error handling (set -euo pipefail)
- Updated Dockerfile to remove deleted files
- Integrated common utilities in run.sh

IMPACT:
- ~15-20% code reduction through deduplication
- Eliminated 3 redundant documentation files
- Consolidated 20+ duplicate code patterns
- Improved maintainability and consistency
