Handle cache storage overflow

[Tzal3x]

Description

We should handle the case where we attempt to store new entries to the service worker's cache but it is full.

From the MDN docs:

Attempting to store more than an origin's quota using IndexedDB, Cache, or OPFS, for example, fails with a QuotaExceededError exception.
Web developers should wrap JavaScript that writes to browser storage within try...catch blocks. Freeing up space by deleting data before storing new data is also recommended.

Therefore, we should add a try/except block on "save to cache" attempts, looking out for a QuotaExceededError and either:

• Replace the oldest entry of the cache with the new one
• Replace the less frequently used entry of the cache
• or something else?
