[CHORE]: Update modebar button names to be more accurate/consistent

[camdecoster]

Description

Update existing modebar button/group names to be more accurate/consistent.

Three related inconsistencies in how modebar buttons are named:

• resetViewSankey reports a different name than its key. It is registered as modeBarButtons.resetViewSankey but carries name: 'resetSankeyGroup' - the only mismatch among the 37 buttons. Removing it therefore requires modeBarButtonsToRemove: ['resetSankeyGroup'], while config.modeBarButtons groups use 'resetViewSankey'.
• _cat: 'reset' matches only resetGeo. It reads like a category but leaves resetViews, resetScale2d, resetViewMap, and the sankey reset in place.
• _cat: 'resetView' matches only resetViewMap, so it misses the sankey reset despite the name suggesting otherwise.

All of these strings are advertised in the layout.modebar.remove enumeration (48 entries), so they are public API.

Why should this change be made?

Users reasonably expect a button's removal string to match its key, and a category alias to cover a family. Today remove: 'reset' and remove: 'resetView' silently no-op on most reset buttons, and the sankey button can only be removed by a name that appears
nowhere else. Compare the aliases that do behave as categories: zoom (2 buttons), pan (2), zoomin / zoomout (3 each), hoverclosest (4).

Scope

• src/components/modebar/buttons.js - name on resetViewSankey, and the _cat values for reset / resetView.
• src/components/modebar/constants.js builds foreButtons from name + _cat, so any change regenerates the schema enumeration (npm run schema, committing test/plot-schema.json and src/types/generated/schema.d.ts).
• src/types/core/layout.d.ts - ModeBarDefaultButtons currently lists both resetViewSankey and resetSankeyGroup

Notes

• All of these changes are breaking
• Nothing is wrong with the current code, but it can be confusing
• _cat casing is inconsistent (hoverCompare, resetCameraDefault, resetView vs hoverclosest, zoomin, autoscale) and should be addressed at the same time (though it's only cosmetic)
• Every item breaks working code - renaming the sankey name invalidates modeBarButtonsToRemove: ['resetSankeyGroup'], and widening the _cat aliases makes existing remove calls take out more buttons. So this belongs in a major release; v4 is the window if it's wanted at all. Separately, _cat casing is inconsistent (hoverCompare, resetCameraDefault, resetView vs hoverclosest, zoomin, autoscale) - cosmetic only, since matching lowercases both sides.
