fix(cache): Fix compression and decompression format mismatch

[zharinov]

Changes

• Don't overload compressFromBase64() and decompressFromBase64() with JSON parsing.
• Instead, make them perfectly symmetric and handle JSON encoding outside, just like it was before regression was introduced in refactor: Deprecate compression with base64 encoding #26711.

This PR should prevent from throwing at JSON.parse() which most probably caused constant cache miss condition.

Context

• Ref: Big performance hit introduced in 37.139.4 #27019
• Supersedes: fix: redis cache deserialization does not work on strings #27020

Looks good to me, compression and decompression are symmetrical again.
