docs(audit): Driver.S7.Cli.md — verb/flag accuracy + ordinal fix

Browse Source 
CODE-REALITY:
- Line 7: "Fourth of four" → "Fourth of six"; there are 6 driver CLIs
  (Modbus, AbCip, AbLegacy, S7, TwinCAT, FOCAS); confirmed by
  src/Drivers/Cli/ project count.
- read section: removed the `DB10.STRING[0] -t String --string-length 80`
  example that documented an unusable code path.  String (and Int64,
  UInt64, Float64, DateTime) live in S7DataType but are blocked in
  S7Driver.UnimplementedDataTypes; any attempt returns BadNotSupported
  (src/Drivers/ZB.MOM.WW.OtOpcUa.Driver.S7/S7Driver.cs:327-333 and
  :450). Added an explicit "not yet implemented" note with the
  source location so readers know why those types are omitted.

STRUCTURAL: no rows in links-report.md for this doc.
STALE-STATUS: no state words found.
INLINE COMPLETENESS: no inventory-diff gaps for this doc.

### `read`
Supported types: `Bool`, `Byte`, `Int16`, `UInt16`, `Int32`, `UInt32`, `Float32`.
`Int64`, `UInt64`, `Float64`, `String`, and `DateTime` are defined in `S7DataType` but
**not yet implemented** — the driver rejects them at initialisation and any read or write
returns `BadNotSupported`
(`src/Drivers/ZB.MOM.WW.OtOpcUa.Driver.S7/S7Driver.cs` — `UnimplementedDataTypes` set).
