v3(s7): apply Modbus RawTags exemplar to the S7 driver

Rename S7EquipmentTagParser -> S7TagDefinitionFactory; TryParse(reference)
-> FromTagConfig(tagConfig, rawPath, out def) (drops the leading-{ heuristic,
keys the def by RawPath, adds inverse ToTagConfig). Replace S7DriverOptions.Tags
(pre-declared S7TagDefinition list) with RawTags (IReadOnlyList<RawTagEntry>);
the driver builds its RawPath->def table from RawTags at Initialize via the
factory (skip+log on miss), resolver is byName-only, DiscoverAsync + init guards
+ address pre-parse now run off that table. Factory retires the pre-declared DTO
tag path (RawTags binding only). Cli BuildOptions serialises typed defs to
RawTagEntry. Tests migrated to a S7RawTags helper + FromTagConfig; parser test
files renamed. Coordinator's EquipmentTagConfigInspector S7 rename left to Wave-B
coordinator; Driver.S7.IntegrationTests (Docker-gated) left red per scope.

Driver.S7 + Cli build green; Driver.S7.Tests 264/264, S7.Cli.Tests 49/49.
