fix(did): allow sorting dataset replicas by replication progress

[Vrohs]

By submitting this PR, I confirm I have followed the Contributing Guide.

Description

Replication Progress on the dataset replicas table could not be sorted. It had sortable: false, and no field and no valueGetter, so removing the flag on its own would have sorted on nothing.

ProgressBarCell computed the percentage inline. This pulls that out into getReplicationPercentage and uses it both to render the bar and as the column's sort value, so the two cannot drift apart. An empty dataset reports 0% rather than dividing by zero.

Two side effects of giving the column a value, handled here:

• Its filter, which defaultColDef renders on every column, was previously a no-op. Left alone it would have become a text filter matching a raw float, so it is set to agNumberColumnFilter.
• With no field the column was addressed by position (col-id="0"). Added an explicit colId, matching colId: 'actions' / colId: 'state' elsewhere, so sort state can reference it stably.

On the rest of the issue: RegularTable sets sortable: true in its defaultColDef and StreamedTable renders RegularTable, so every table already inherits sorting. I checked the rendered headers in Storybook for the RSE, rule, subscription and DID list views and the approve-rules table, and every data column is sortable. Of the explicit sortable: false opt-outs, six look correct and are left alone: two checkbox-selection columns, two Actions button columns, and the FTS Monitoring / DDM Dashboard link columns, which have no value to sort on.
