Issue Description

When a renewable technology sets corine: false in the config (typical for offshore technologies), the script crashes with TypeError: argument of type 'bool' is not iterable at every line that checks "key" in corine.

This affects determine_availability_matrix_MD_UA.py.

Reproducible Example

1. Set `corine: false` for any offwind technology in the config:


renewable:
  'offwind-dc':
    corine: false
    copernicus: {}


2. Run the availability matrix rule:


snakemake solve_elec_networks --configfile ./config/config.yaml --cores 14


3. Produces the following error traceback:


File "determine_availability_matrix_MD_UA.py", line 63, in <module>
    if "grid_codes" in corine:
       ^^^^^^^^^^^^^^^^^^^^^^
TypeError: argument of type 'bool' is not iterable

Expected Behavior

Proposed fix:

After the line where corine is read from the config, add a type guard that converts non-dict values to an empty dict. This way all downstream "key" in corine checks simply evaluate to False, which is the intended skip behavior.

corine = config.get("corine", {})

# Add this line
if not isinstance(corine, dict):
    corine = {}

Replace this line.
