fix: remove hardcoded path and load from .env in handle-issue-ts.sh

Replace hardcoded AGENT_MANAGER_DIR with dynamic loading from .env file
using AGENT_MANAGER_PATH variable for better environment flexibility.

**Changes**:
- Load AGENT_MANAGER_PATH from .env file at multiple possible locations
- Try common paths: /home/claude/agent-manager/.env, /data/agent-manager/.env, $HOME/agent-manager/.env
- Fallback: Auto-detect from script location if .env not found
- Log which configuration source was used for debugging

**Benefits**:
- No hardcoded paths - works across different environments
- Respects .env.example configuration pattern
- Automatic fallback ensures script still works without .env
- Makes deployment to different servers easier

**Usage**:
Set in .env file:
```
AGENT_MANAGER_PATH=/your/custom/path/agent-manager
```
