v3(ablegacy): apply Modbus exemplar — RawTags delivery + RawPath mapper

- Rename AbLegacyEquipmentTagParser → AbLegacyTagDefinitionFactory; TryParse →
  FromTagConfig(tagConfig, rawPath, out def). Drop the leading-{ heuristic and the
  deviceHostAddress key; def.Name = rawPath. Add inverse ToTagConfig. Keep strict-enum
  guards + Inspect.
- Options: Tags(IReadOnlyList<AbLegacyTagDefinition>) → RawTags(IReadOnlyList<RawTagEntry>).
- Driver: _tagsByRawPath (Ordinal); byName-only resolver; build table from _options.RawTags
  via FromTagConfig, threading WriteIdempotent + resolving RawTagEntry.DeviceName to the
  owning device host (ResolveDeviceHost; TODO(v3 WaveC) for the live Device-row host).
  DiscoverAsync + family-profile validation iterate the built table. Probe picks its address
  from RawTags via the mapper.
- Factory: retire the pre-declared tag DTO path; bind List<RawTagEntry>? RawTags; keep Devices.
- Cli BuildOptions: deliver typed defs as RawTagEntry via ToTagConfig.
- Tests: AbLegacyRawTags helper; migrate Tags= → RawTags; parser tests → FromTagConfig;
  equipment-ref driver/ResolveHost tests re-authored as RawTagEntry + read by RawPath.

Driver+Contracts+Cli green; 213 driver + 36 Cli tests pass.
