fix(generator-networks-creator): repair zero viewport dimensions before training

[sk8kpwhrjt-creator]

Addresses #6.

@algora-pbc /claim #6

Summary

This follows the review feedback on #544 and #549 by keeping the fix out of runtime generation and out of the zod schema rejection path.

The patch repairs zero viewport dimensions in collected fingerprint records before they are deconstructed into the fingerprint training dataset:

• infer zero innerWidth / innerHeight from the same record's screen, available screen, and outer window dimensions
• infer zero clientWidth / clientHeight from the repaired inner viewport dimensions
• preserve already collected positive viewport/client values unchanged
• drop only fingerprint records that still contain unrepaired zero viewport dimensions after the repair step

That prevents future fingerprint networks from learning the innerWidth: 0, innerHeight: 0, clientWidth: 0, clientHeight: 0 shape reported in #6 without rejecting the bulk of the existing corpus.
