[FEATURE] Table: adds a table-wide Enable Sorting option

[mixturesolutions]

Description

Implements perses/perses#4204
Adds a table-wide Enable Sorting option in General Settings so all columns are sortable by default, without configuring each column individually:

• New enableSorting on Table options
• Columns inherit the general default; Column Settings can still override
• Toggling General Settings re-applies the default to all columns (clears stale per-column flags)
• Column editor only persists enableSorting when it differs from the general default

Screenshots
