Add dedicated Laparoscopic rendering scripts

[carotam]

Description

This PR introduces support for the Laparoscopic project alongside the existing Colon configuration, by adding three new scripts rather than modifying the originals.

Motivation

• The existing scripts/install_and_enable_addons_render.py is tightly coupled to the Colon project’s node setup and cannot produce labels for Laparoscopic renders.
• Rather than risk breaking Colon workflows, we’ve created parallel “laparoscopic” versions of the install-and-enable and runner scripts.

What’s Changed

1. New install-and-enable script

• scripts/install_and_enable_addons_render_laparoscopic.py
• Forked from the original install script and adapted for the Laparoscopic project, whose node groups don’t allow a “material” input, so we can’t set materials programmatically as we do in the Colon project.
  Note: Both install scripts could eventually be unified behind a --project flag, pending some refactoring and testing.

2. New single-run runner

• scripts/run_laparoscopic_RandomiserBlender.sh
• Duplicate of run_RandomiserBlender.sh, except it invokes the laparoscopic-specific install script.
  Future: We could merge both runners under one script with a --project flag.

3. Batch-run utility

• scripts/run_laparoscopic_multiple_times
• Loops over a range of seeds to produce multiple renders and labels in one go.

How to run:

./run_laparoscopic_multiple_times \
  [NUMBER_OF_SAMPLES]  \
  [JSON_IN] \
  [BLENDER_FILE_PATH] \
  [BLENDER_FILE_PATH_LABEL]
  [PREFIX_OUTPUT_NAME]

Example to create 1000 images with labels:

• Using the parameters from path/to/parameters.json the script will generate 1000 images and 1000 labels

./run_laparoscopic_multiple_times \
  1000 \
  "path/to/parameters.json" \
  "path/to/blender_to_render.blend" \
  "path/to/blender_to_label.blend" \
  "my_experiment"

Looks good to me (LGTM), thank you for your contribution. I'm happy to merge this assuming the tests pass.
