fix(funnel/waterfall/pie/sunburst): respect textinfo token order

[camdecoster]

Summary

Resurrects the work from #7752 (closed because it's a breaking change; targeting v4.0 here so it can ship in the next major release).

Replaces hardcoded hasFlag() checks in calcTextinfo / formatSliceLabel with a loop over the user-specified textinfo tokens so they render in the requested order. Applies to funnel/waterfall (bar/plot.js), pie, sunburst, and indirectly treemap, icicle, and funnelarea (which reuse formatSliceLabel).

Note: per @archmoj's comment on #7752, the flaglist attribute type spec explicitly says token order should not affect output. Either the spec / coerce.js flaglist handling needs to be relaxed to permit ordered tokens, or textinfo needs a new orderedflaglist-style coerce type. Filing this PR against v4.0 to gate that decision behind a major-version bump.

Before:

• textinfo="percent initial+value" → "1000 100.0%"

After:

• textinfo="percent initial+value" → "100.0% 1000"

Test plan

• Lint passes (npm run lint)
• New jasmine tests added for funnel/pie/sunburst to assert token order is respected
• Existing restyle and base assertions updated in sunburst/treemap to reflect new ordering
• Image baselines may need regeneration in CI (display-text_zero-number, funnelarea_with_other_traces, icicle_, sunburst_with-without_values, treemap_); v4.0 baselines kept here so CI can flag the actual deltas
• Verify failing image baselines are expected order-change diffs, not unrelated rendering shifts

Closes #7751. Supersedes #7752.
