Backend: Limit the number of nearest recycling bins displayed to 5

[neozhixuan]

Context
We are facing an issue; there are 12000 recycling bins in Singapore, and if the user selects an item belonging to a recycling bin (anything in RECYCLABLE category), it displays all recycling bins within 3km by default. We want to limit that to just 5 nearest bins for ease.

Task

• Adjust the code in the hooks folder that calculates and saves the nearest recycling facilities as a JS object such that at most 5 Blue Bins can be added
• Ensure that the change works, in the map page
