- Account model gains parentId (self-referential, 3 levels: TopCategory → SubCategory → Item)
- DB migration: adds parentId FK column to Account table
- Code format changed from PREFIX-NNN to 6-digit numeric (e.g. 100101)
- Seeded all 300+ accounting codes from the official chart (Rev. 01/251227) across
7 top categories: Capital Expenses, Business Development, Office Admin, Project
Expenses, Manning, Technical, Bunker/Lubes
- Admin Accounting Code page: collapsible tree view (top category > sub-category > items),
inline search, Add/Edit dialogs with parent selector and 6-digit code field
- All PO forms (new, edit, import, manager-edit): accounting code dropdown now shows
only leaf items grouped in <optgroup> by sub-category, labelled "TopCat › SubCat"
- Seed data updated: old flat account codes replaced by mapped leaf codes from new hierarchy
