What changed and why

Three fixes so a Japanese or Korean financial_services bank writes, checks and respells amounts and terms the way those languages do. Three commits:

1. Yen and won are whole amounts with the unit after. Neither currency has a minor unit, and both languages write it straight after the number. For a ja or ko number format, format_amount writes 1,234,567円 and -50,000원, where it wrote 円1,234,567.00. A fractional amount keeps its two decimals, and percentages keep the 0.25% form both languages use.

2. The numeric check reads units of 10^4. Japanese and Korean count large amounts in 万/만 (10^4) and 億/억 (10^8): ten million yen is 1,000万円, and 150 million won is 1억 5,000만 원. validate-assets now accepts these renderings of a typed value, as it accepts lakh and crore, and still fails a different value.

3. Respelled forms are found inside Japanese and Korean text. Japanese runs words together and Korean writes particles onto them (직불카드를), so a form in either script was missed wherever another word or a particle touched it. An edge of a form in Japanese or Korean script now matches whatever character it meets, and any other edge still needs a word boundary: ATMカード is found in 新しいATMカードが but not in XATMカード.

How it was verified

Each commit passes on its own:

• uv lock --check, make check-all, make check-license-headers, make check-doc-links, make check-notebooks-clean, make smoke and make test exit 0 at all three commits. make test reports 4379, 4380 and 4381 passed.
• make check-dist and make check-extensions exit 0 at all three commits.
• New tests cover yen and won amounts through Institution.format_money, including a negative and a fractional amount, with percentages unchanged; 万, 億, 만, 억 and 천만 renderings counting as faithful, with a different value in the same form still failing; and respelled forms found and rewritten inside Japanese and Korean words, with a Latin edge still needing a word boundary. Each new test fails on main.
• Shipped banks are unaffected. usersim validate-assets --domain financial_services reports identical results for all six banks at every commit. Across all 30 finance corpora (13,310 titles and bodies), the en_GB respellings give the same matches and rewrites as on main.

make health-check wasn't run: the change makes no model calls.

Results impact

None for the shipped banks: money formatting, validation results and respelling are unchanged in every one of them.
