## Issue
Accumulation of so many strings for a "successful tip" that it is getting annoying to re-translate them for minor changes.
## Change
- Consolidate and re-use strings.
- Make the tip string currency-agnostic so we don't have to touch it again. The amount and currency is moved to the `subMessage`.
- Fix spacing being incorrectly enforced through i18n (it should be done via code/css).
