[horde] CalDAV synchronize errors and Redis error

[R.J.Baart at Prompt.nl]

I think it is typical a php 8.4 error:

Changing vendor/horde/cache/lib/Horde/Cache/Storage/Hashtable.php line 69:

from:

    $res = $this->_hash->get($query);

to:

    $res = $this->_hash->get((string) $query);

And lines 87+88

from:

    $this->_hash->set($this->_getKey($key), $data, $opts);
    $this->_hash->set($this->_getKey($key, true), time(), $opts);

to:

      $this->_hash->set($this->_getKey($key), $data, (int) $opts);
      $this->_hash->set($this->_getKey($key, true), time(), (int) $opts);

Solves these problems
