One-window install: profile, wifi, USB flash and pairing hints (0.2.27)

"Nieuw scherm" used to span two dialogs plus a copy/download of the
installation YAML. It is now one dialog: board, name (node name derived,
editable), wifi only when secrets.yaml lacks it, the detected USB port,
and Installeren. The add-on writes the profile with unique API/OTA keys,
merges just the missing wifi lines into secrets.yaml (comments and other
secrets untouched, result re-parsed before writing), then builds and
flashes with the live ESPHome log and stage in the same dialog; a failed
build offers a retry without a second profile. The YAML download
endpoint is gone: the profile already lives in the ESPHome folder.

Pairing happens in Home Assistant itself, so the done view and a sidebar
card per not-yet-paired profile say so, with a button to Apparaten &
diensten, the API key to copy and the reminder to allow HA actions.
One profile per screen; the dialog says that too.

Tests: wifi merge cases, install pre-checks, pending list, profile
metadata; the date-anchored hourly forecast test now follows the clock.
Firmware 0.2.22 stays current.
