[ECO] Plant growth rates reversed for Green and Industrial eco footprints

Issue Description:
Plants grow slower when a neighborhood has a Green eco footprint and faster when the footprint is Industrial. This is the inverse of the intended behavior, as a Green environment should promote healthier, faster plant growth while an Industrial environment should hinder it. The bug affects all plant types on lots within the affected neighborhood.

Expected Behavior:
Plants should grow faster in neighborhoods with a Green eco footprint and slower in areas with an Industrial footprint. A Green environment provides clean air and healthy conditions, which should benefit plant life, while pollution and smog from an Industrial area should stunt growth.

Steps to Reproduce:

1. Have a Sim plant a garden on a residential lot in a neighborhood.
2. Shift the neighborhood's eco footprint to Green (using green objects, NAPs, etc.).
3. Monitor the growth time of the plants.
4. Shift the same neighborhood's eco footprint to Industrial (using industrial objects, generators, etc.).
5. Plant the same type of plant and monitor its growth time.

Actual Result:

• Plants in the Green neighborhood take longer to grow.
• Plants in the Industrial neighborhood grow faster.

Additional Notes:

• The Sims Wiki confirms this is a known bug: "Note that due to a bug, Industrial Eco Footprint and Green Eco Footprint have their effects on plant growth reversed. Plants will grow slower in Green environments and faster in Industrial environments due to a decay modifier being mistakenly backwards".
• The bug is due to a "decay modifier being mistakenly backwards" in the game's code.
• It has been an unresolved issue since the release of the Eco Lifestyle pack.
• A neighborhood's eco footprint can be tracked via the icon near the game clock, categorized as Green, Neutral, or Industrial.

Impact:
Moderate to High. This bug fundamentally undermines a core gameplay loop of the Eco Lifestyle pack. It discourages players from achieving a Green footprint, as it penalizes them with slower plant growth. It also removes a key reward for sustainable gameplay, directly conflicting with the pack's theme of environmental improvement.
