Add tests for shared frontend helpers; fix link restore slot check

Restoring links after a failed change checked the source node but not
its output slot, so a link from another output of the same node could
be kept. 29 new tests cover scrub math, graph links, panel sizing,
Civitai parsing, brush math and widget card values.

 ### Video Crop + Rotate + Pad → Frame
 
 Picks one frame from a video, then gives you the same rotate, crop and pad controls as the image node, plus an optional megapixel resize. Scrub to the frame with the playhead on the node; the editor adds frame-by-frame stepping and playback. It returns the transformed `image`, a `mask` of the added area, a `stitcher`, the chosen `original` frame, and the output `width` and `height`. For a whole clip, use the Clip version below.

-# Load Audio
-
-Loads a sound file and hands on only the part you pick. Use it for a voice
-clip, a song or any sound a video model or a save node takes, when you want
-one part of the file and not the whole thing.
-
-The node shows the whole file as a wave, so you can see where the loud parts
-are. The part that comes out is bright. Drag the white **IN** and **OUT**
-handles to set where it starts and stops, drag the bright part to slide it,
-or click somewhere else on the wave to move it there. You can also type a time
-under the wave, in seconds (`12.5`) or minutes and seconds (`1:02.5`).
-
-Press **▶** to hear only the part that comes out. **LOOP** plays it again and
-again.
-
-## Max length
-
-Set **Max length** to the longest sound the next step can take, such as the
-length of the video you are making. The start stays where it is, and anything
-past the limit turns red with a dashed line where it is cut. Next to OUT,
-the node shows how long the sound that comes out is, such as `15.0 s`. It
-turns red when part of your pick is cut; hold the mouse over it to see how
-much, and click it to move OUT to the cut. Play stops at the cut, so what you
-hear is what comes out. `0` means no limit.
-
-Max length can be wired. When the wire comes from a number node such as
-Float 🆎, the wave shows the cut for that number; otherwise the length's tooltip says
-`max wired` and the run still cuts the sound to the wired length.
-
-## Controls
-
-- **Source** (`audio`): a sound file in ComfyUI's input folder. **Upload**
-  adds one. Videos are listed as well, for their sound.
-- **Max length** (`max_seconds`): the longest the sound may be, in seconds.
-  `0` means no limit.
-- **IN** (`start_seconds`): where the sound starts.
-- **OUT** (`end_seconds`): where the sound stops. `0` means the end of the
-  file.
-
-## Outputs
-
-- `audio`: the part you picked, for any node that takes `AUDIO`.
-- `seconds`: how long that sound is.
-
-## Technical details
-
-- Only the picked part is returned. Decoding starts at the beginning,
-  discards sound before IN and stops at OUT or the Max length cut. A late
-  selection in a long recording takes longer to load.
-- Preview playback pauses when you switch tabs or hide the page.
-- The sound keeps its own sample rate and channels.
-- A start past the end of the file stops the run with a message that says so.
-- The wave is drawn in the browser from the file itself; nothing extra is
-  stored with the workflow besides the four values above.
