Support integers as cell values from Sheets API

[Copilot]

The Sheets API returns numeric cell values as JSON integers, not strings. ValueRange decoded values as [[String]], causing decoding to fail silently for any cell containing a number.

Changes

• ValueRange.swift — Added a custom init(from:) with a private AnyCellValue helper that decodes each cell as String → Int → Double, converting numbers to their string representation

// JSON from Sheets API: {"values":[["key","en"],["count",42]]}
// Previously: decoding failure
// Now: ValueRange.values == [["key", "en"], ["count", "42"]]

• ACKLocalizationTests.swift — Added tests covering integer cells, double cells, mixed rows, and end-to-end flow through transformValues
