feat: page, hash and rootline caches in Redis again, as on TYPO3 10

Browse Source 
Since every page view goes through TYPO3 13, the page cache is on the hot
path; TYPO3 10 kept it in Redis, TYPO3 13 had it in MySQL. Same socket and
options as TYPO3 10, but databases 3-5 instead of 0-2, which may still
hold TYPO3 10 entries in a format TYPO3 13 must not read. DDEV gets the
redis add-on for the same setup locally.

Without a Redis connection the backend logs an alert and misses, so pages
still render (slower); a missing PHP redis extension, however, fails hard.
