Add range/cooktop-oven combo support (issue #44)

TP1X_DA-KS-RANGE-0102X (model NSI6DG9100SRAA) reports no oneUiVersion and
previously fell through to the unknown-device fallback, leaving /connected,
/cooktop/spec, /cooktop/settings/status, /cooktop/status, and /oven/spec
unbound. Add a 'range' device registry that reuses the oven family's
cavity/setpoint/mode/operational-state/door capabilities and adds a new
cooktop.py module modeling per-burner power level, state, and hot-surface
entities (gated so unreported burner slots don't appear), plus a hot-surface
auto-shutoff config sensor. Route range/cooktop models to it via a
'-RANGE-' modelNum token, mirroring the existing RAC/PRAC air-conditioner
fallback pattern.

The dryer (DA_WM_TP1_21_COMMON) pause/stop buttons mentioned in the same
issue are working as intended -- the reporter confirmed that's an expected
in-person-only limitation, not a bug.

+Unlike the rest of the OCF surface, these hrefs use plain camelCase field
+names (no `x.com.samsung.da.` prefix) -- `/cooktop/status/vs/0` already
+looks like a vendor resource migrated onto OCF-standard-shaped field naming.
+
+`/cooktop/status/vs/0` carries every burner's live state in one `burnerList`
+array (indexed by `burnerNumber`, not by a separate href per burner like
+fridge ice makers), so per-burner entities are hardcoded up to MAX_BURNERS
+and gated by exists_fn against whichever indices the device actually
+reports -- harmless over-declaration, per common.py's UNIVERSAL note, since
+an index absent from burnerList just never binds.
+
+Write surfaces here are unproven (no live device to verify against, same
+caveat as oven.py's RMW writes) -- power level uses the same read-modify-
+write pattern already proven safe elsewhere in this codebase (oven setpoint,
