Before this commit, formatters like `formatMonetary` and `formatFloat` weren't loaded in the assets front-end. This commit introduces `formatAmount` ( `formatMonetary` calls `formatAmount` but makes some prior processing to deduce the currency from the field) and makes `formatAmount` and `formatFloat` accessible from any front-end application. Note: The currencies were added in the front-end session info because they are needed in `formatAmount`. closes odoo/odoo#133824 Related: odoo/enterprise#46658 Signed-off-by: Valentin Chevalier <vcr@odoo.com>
