Fix dashboard /web Internal Server Error by resolving templates directory to absolute path

[podcctv]

Motivation

• The dashboard router used a relative template directory which could cause TemplateNotFound (Internal Server Error) when the process CWD was not master-api, so templates must be loaded via a stable absolute path.

Description

• Change templates = Jinja2Templates(directory="static") to compute an absolute path with _STATIC_DIR = Path(__file__).resolve().parents[2] / "static" and initialize Jinja2Templates(directory=str(_STATIC_DIR)) in master-api/app/core/globals.py so template loading is independent of process working directory.

Testing

• Ran python -m py_compile master-api/app/core/globals.py which succeeded without syntax errors.
• Verified the resolved static path with PYTHONPATH=master-api python - <<'PY' ... which printed the _STATIC_DIR and confirmed it exists().
