API call counts just under a magnitude display as 1000K #8803

Describe the bug

Found in the frontend source on main. The usage page and the organisation API limit banner shorten API call counts with Format.shortenNumber. When a count rounds up to the next magnitude, the shortened value keeps the smaller suffix:

This is most visible for an organisation close to a 1M limit, where the usage meter reads 1000K / 1M.

Steps To Reproduce

1. In the frontend, call Format.shortenNumber(999950) from common/utils/format.ts.
2. The result is 1000K.

Expected behavior

The value moves to the next suffix after rounding, so 999950 displays as 1M.
