Vuu Table UI is showing raw values instead of display value

## Feature Request

### Description of Problem:
Server is providing UI the raw values in rows, however we would like to display it differently
i.e. if raw data is a FIX message, tag 35 value = 0, 1, 2 etc
but on UI we would like to see 0 = Heartbeat, 1 = Test Request, 2 = Resend Request etc

### Potential Solutions:
When server is sending the columns, shall we have the map of possible values vs display values (per column), if this map is not defined, UI shall show the raw value

Start at the Vuu Table UI column and row rendering entry points, then trace how server-provided columns and raw row values reach the display. Define how per-column raw-to-display mappings are supplied and rendered, while preserving raw values when no mapping exists. Done means FIX values such as 0, 1, and 2 display their configured labels without changing unmapped values; no files or tests are named in the issue.
