fix(homend_royaltea_kettle): adjust for user observations

The portal documentation seems to be misleading for some dps, and
there are a few dps that seem unimplemented.

- use dp 4 as backup for dp 8 temperature, as the latter seems unused.
  I implemented it as a backup in case there are some settings where dp 8
  becomes useful.
- use dp 104 as backup for dp 15 status. The values for this are not
  documented, but @ErsinErce has figured some out. It seems dp 15, while
  fully documented is not sent.

Issue #3341
