Summary: Changes auto-generated summary table IDs from e.g. `GristSummary_6_Table1` to `Table1_summary_A_B` (meaning `Table1` grouped by `A` and `B`). This makes it easier to write formulas involving summary tables, make API requests, understand logs, etc. Because these don't encode the source table ID as reliably as before, `decode_summary_table_name` now uses the summary table schema info, not just the summary table ID. Specifically, it looks at the type of the `group` column, which is `RefList:<source table id>`. Renaming a source table renames the summary table as before, and now renaming a groupby column renames the summary table as well. Conflicting table names are resolved in the usual way by adding a number at the end, e.g. `Table1_summary_A_B2`. These summary tables are not automatically renamed when the disambiguation is no longer needed. A new migration renames all summary tables to the new scheme, and updates formulas using summary tables with a simple regex. Test Plan: Updated many tests to use the new style of name. Added new Python tests to for resolving conflicts when renaming source tables and groupby columns. Added a test for the migration, including renames in formulas.
