Remove dead ValidatorGenerator (#319) and refresh local Spine SDK dependencies

[alexander-yevsyukov]

Summary

Three related pieces of housekeeping on this branch:

1. Remove dead ValidatorGenerator/ApplyValidator — resolves Remove dead ValidatorGenerator/ApplyValidator (unreachable, superseded by ValidatorRegistry) #319.
2. Refresh local/ Spine SDK dependencies to their latest published snapshots.
3. Bump the published version 2.0.0-SNAPSHOT.449 → .450 and regenerate dependency reports.

1. Remove dead code (closes #319)

ValidatorGenerator and its nested ApplyValidator were never instantiated — no
direct construction, no reflection, no ServiceLoader (the module's only
ServiceLoader.load targets ValidationOption), and no META-INF/services entry.
The nested-message validation they were designed to generate at compile time is
handled at runtime by io.spine.validation.ValidatorRegistry.validate(...) via
ValidationCodeInjector, so the class was superseded and unreachable.

Removing the file also drops its file-local ValidatorClass/MessageClass
typealiases, which had no other users; the five expression helpers it imported
(constraintViolation, mergeFrom, orElse, resolve, stringify) remain used
across other files, so nothing new becomes dead.

Closes #319.

2. Refresh local/ Spine SDK dependencies

Object	Old → New
Base	.421 → .423
Compiler	.059 → .060
Logging	.419 → .422
Time	.242 → .244
ToolBase	.402 → .403
Validation	.446 → .449

CoreJvm is intentionally held back at .381. Its latest snapshot (.411)
removes io.spine.server.entity.alter, still used by ~11 option views in the
context module — adopting it fails :context:compileKotlin with Unresolved reference 'alter'. Moving to a newer CoreJvm needs a coordinated alter migration,
which is out of scope for a version refresh and should land as its own change.

3. Version bump + reports

• version.gradle.kts: validationVersion 2.0.0-SNAPSHOT.449 → .450.
• docs/dependencies/pom.xml and dependencies.md regenerated to match.

Verification

• ./gradlew build dokkaGenerate — BUILD SUCCESSFUL (full compile + test suite + Dokka; the removal breaks no KDoc links).
• Pre-PR reviewers all APPROVE with zero Must-fix / Should-fix: dependency-audit, spine-code-review, kotlin-engineer, review-docs.

Note for reviewers

Pre-existing, unrelated working-tree changes (.idea/misc.xml, docs/_examples) were deliberately kept out of this PR.
