feat: widen all Zod schema constraints for power users

Raise all artificially low max values on tool settings:
- stitch: grid→100, gap→1000, border/radius→500
- split: grid→100x100
- collage: zoom→10, gap→500, radius→500
- watermark: fontSize→1000
- border: width→2000, radius→2000, shadow→200
- qr: size→10000
- gif: dimensions→16384
- passport: dpi→1200
- sharpening: amount→1000
- pdf/svg: dpi→2400, dimensions→65536
- vectorize: precision→16
- bulk-rename: pattern→1000
- image-to-pdf: margin→500
- pipeline: name→255, description→2000
