Description

Addresses #569: random seed and variation-seed dice previously generated values too large to copy accurately into AUTOMATIC1111 web UI numeric fields.

• Match AUTOMATIC1111 random generation: 0–4,294,967,293 inclusive.
• Validate manual A1111/SwarmUI seeds against JavaScript’s safe integer range, with inline feedback and generation submission checks. Empty input and -1 still request randomness; other seed controls retain their Long range.
• Add a SeedValidator interface with a separate internal implementation, constructor-configured limits and Koin bindings for both generation screens.
• Synchronize validation messages across all six locales.

Validation

• 56 tests pass: 38 seed regression tests and 18 existing sampler tests.
• Android full debug assembly and iOS Simulator compilation pass.
• Pixel 3a XL, Android 12: checked both seed fields in txt2img/img2img, manual boundary and oversized input, malformed input, and clear/dice recovery.
• Actual A1111 image reproduction and iOS runtime behavior remain untested.

Checklist

• I have ensured this PR does not contain any breaking changes for existing functionality
• I have added automated tests that cover the new behavior and removed obsolete tests and code
• I have added documentation for any new public APIs and update existing documentation for any changes to public APIs
