Fix: Improve Manual Decimal Input Precision and Use SingleActivator

[saulrmzlpz]

Justification

After performing some tests on manual quantity entry, I noticed that allowing decimal input becomes difficult when precision exceeds two decimal places. For example, trying to enter “0.935” using the keyboard causes the field to auto-complete with “0.900” as soon as “0.9” is typed, making manual entry challenging.

Additionally, TODO changes were implemented to use SingleActivator.

Note: Based on these changes, some tests were commented out and need to be reviewed.

Changes:
Bump version to 0.13.2
Update SpinBox with improved decimal formatting
Use SingleActivator for keyboard shortcuts

Hi, my apologies that this package hasn't been actively maintained for a while. Could we start with the SDK updates, formatting changes, refactoring etc. in separate PRs to avoid mixing them up with the actual fix, please?
