- Letter Head fixture renders company details (logo, name, tax id, address,
phone, email) from the printed document's company via a jinja helper
instead of hardcoded values; falls back to the default company for
doctypes without a company field.
- Register fixtures in hooks (Letter Head, Address Template); they were
never imported before.
- Preserve the fixture's `source = HTML` on import: LetterHead.before_insert
forces "Image" and fixture import is delete + insert.
- Thailand Address Template: two-line address, phone/fax/email lines kept.
