Fix variable naming typos in france_example_02.R

[Copilot]

Corrects inconsistent bounding box variable naming in france_example_02.R that used non-standard _bb_llox suffix instead of _bbox.

Changes

• Renamed aot_bb_llox → aot_bbox (5 occurrences)
• Renamed aoi_bb_llox → aoi_bbox (5 occurrences)

Aligns with naming conventions used in france_example_01.R and france_example_03.R.

# Before
aot_bb_llox <- sf::st_bbox(transfor_aot)
west = as.numeric(aot_bb_llox["xmin"])

# After
aot_bbox <- sf::st_bbox(transfor_aot)
west = as.numeric(aot_bbox["xmin"])
