[BUG] findAllotPathsAndValues fails even without %allot fields in createStandardData

[hitman298]

The findAllotPathsAndValues function in @nillion/secretvaults@0.1.6 incorrectly tries to process %allot fields even when they are not present in the data, causing createStandardData to fail with "Cannot convert undefined or null to object" error.

Steps to Reproduce:

1. Create a collection with plain text fields (no %allot in schema)
2. Try to store data without any %allot fields
3. Call createStandardData with plain text data

Expected Behavior:
Data should be stored successfully as plain text

Actual Behavior:
Fails with TypeError: Cannot convert undefined or null to object at findAllotPathsAndValues

Environment:

• Library: @nillion/secretvaults@0.1.6
• Network: Testnet
• Node.js: Latest

Test Code:

// This fails even with plain text data
const result = await builder.createStandardData({
  collection: collectionId,
  data: {
    _id: randomUUID(),
    name: 'Plain Text Name', // No %allot fields
    email: 'test@example.com' // No %allot fields
  }
});

Additional Notes:

• Collection creation works perfectly
• Data reading works perfectly
• Builder registration works perfectly
• Only data storage (createStandardData) is affected
• Affects both single objects and arrays of data
