fix(data-format): ajv warnings

[alexandre-abrioux-rf]

This fixes AJV's warnings when initializing the library:

  console.warn
    strict mode: missing type "string" for keyword "pattern" at "#/properties/invoiceItems/items/properties/tax/else/properties/amount" (strictTypes)

      at checkStrictMode (node_modules/.pnpm/ajv@8.17.1/node_modules/ajv/lib/compile/util.ts:212:18)
      at strictTypesError (node_modules/.pnpm/ajv@8.17.1/node_modules/ajv/lib/compile/validate/index.ts:331:18)
      at checkKeywordTypes (node_modules/.pnpm/ajv@8.17.1/node_modules/ajv/lib/compile/validate/index.ts:305:9)
      ...

AJV warns that regex patterns only apply to strings, so they should be explicitly specified in the schema, as we already do for other patterns.

Greptile Summary

This PR adds explicit "type": "string" declarations alongside the "pattern" keywords in the tax.amount conditional (if/then/else) branches of the invoice schema, silencing AJV v8 strict-mode warnings that fire because regex patterns are only meaningful on strings.

• The two additions are in the then and else branches of the invoiceItems[].tax.amount conditional validator, mirroring the style already used for every other pattern-bearing property in the schema.
• No other pattern occurrences in the file were missing their type, so the fix is complete within this schema version.

Confidence Score: 5/5

Safe to merge — the change adds missing type annotations to a JSON schema without altering any validation logic or accepted values.

Both additions simply co-locate "type": "string" next to existing "pattern" keywords. Every other pattern in the schema already had this annotation; the change brings the two conditional branches in line with the rest of the file. Validation behavior is unchanged for valid inputs; the only effect is that AJV strict-mode no longer emits warnings on initialisation.

No files require special attention.

packages/data-format/src/format/rnf_invoice/rnf_invoice-0.0.3.json	Added "type": "string" to both then and else branches of the tax.amount conditional — all pattern keywords in the file now have an explicit type, eliminating AJV strict-mode warnings.
