… of 100000 exceeded" on wide datasets (Backport) (#7940) ## Rationale Backport changes to 26.7 for LabKey/internal-issues#1219 On wide grids (many columns), setting a summary statistic posts the full custom-view JSON to the saveQueryViews action, which is capped at `@JsonInputLimit(100_000)` characters. The per-column field metadata array (fields) plus full column objects blow past that limit and the save fails ("Character read limit of 100000 exceeded"). The fix trims the POST body in `_updateSessionCustomView`: drop the unused top-level fields array and reduce each column to just fieldKey (+ title when present). ## Related Pull Requests - #7800 - #7940 - LabKey/testAutomation#3154 ## Changes - DataRegion call to saveQueryViews does not need to include view 'fields' info in post
