Fix inverted and missing feature checks in lock and lawn mower

[piitaya]

Proposed change

Three feature checks that let the UI dispatch services core rejects.

Lock — state-card-lock renders the open button when the lock does not support LockEntityFeature.OPEN. Supporting locks get no button, non-supporting ones get a button that calls lock.open and raises. The Polymer original used hidden$="[[!supportsOpen]]", a hide condition, and the negation was carried over verbatim when it became a show condition in #18257. The two other buttons in the same file were inverted correctly.

Lawn mower — more-info-lawn_mower guards the icon and label on PAUSE, but _handleStartPause branches on isMowing() alone, so a START_MOWING-only mower shows "Start mowing" while mowing and calls lawn_mower.pause. Extracted a _showPause getter used by the icon, label, service branch and disabled state. _startPauseDisabled also never checked START_MOWING, so a PAUSE-only mower rendered an enabled button calling lawn_mower.start_mowing. Same gap on the start branch of LAWN_MOWER_COMMANDS_BUTTONS.

Core gates all of these: lock.open on LockEntityFeature.OPEN, lawn_mower.start_mowing on START_MOWING, lawn_mower.pause on PAUSE.
