KilianSwissborg b86b297996 [2.x] fix: Preserve '=' in remote cache header values (#9534) ...

**Problem**
`remoteCacheHeaders` entries are parsed in GrpcActionCacheStore.AuthCallCredentials
with h.split("="), which splits on every =. Java's split discards trailing empty
strings, so a Basic auth header such as authorization=Basic dXNlcjpwdw== produces
exactly two elements and matches List(k, v) with the base64 padding silently removed.
The truncated credential is rejected by the cache server with UNAUTHENTICATED.

**Solution**
Split on the first = only, keeping the remainder of the string verbatim as the header
value. The error case narrows to a header containing no = at all.
