Alex Chi Z. 6ad99826c1 fix(pageserver): refresh_gc_info should always increase cutoff (#9862 )

## Problem

close https://github.com/neondatabase/cloud/issues/19671

```
Timeline -----------------------------
         ^ last GC happened LSN
              ^ original retention period setting = 24hr
> refresh-gc-info updates the gc_info
              ^ planned cutoff (gc_info)
         ^ customer set retention to 48hr, and it's still within the last GC LSN
         ^1   ^2 we have two choices: (1) update the planned cutoff to
                 move backwards, or (2) keep the current one
```

In this patch, we decided to keep the current cutoff instead of moving
back the gc_info to avoid races. In the future, we could allow the
planned gc cutoff to go back once cplane sends a retention_history
tenant config update, but this requires a careful revisit of the code.

## Summary of changes

Ensure that GC cutoffs never go back if retention settings get changed.
