Add sorting, filtering, and new columns to WeaponTable

Enhanced the `MudDataGrid` in `WeaponTable` by enabling multiple sorting and filtering while adding new "Faction" and "Immortal" columns. Extended `EntityModel` and `DATA` to support faction and immortal data for the table. Added "Neutral" faction and new entity "Pyre Miner" to the data model.
