Vue3: instances of LabeledInput using v-model.number modifier need to be updated to vue3 syntax

[mantis-toboggan-md]

Describe the bug
It looks like v-model was generally replaced with v-model:value, but not when the .number modifier was used. UnitInputs appear to be working, but LabeledInputs using v-model.number are not. A quick code search shows we have quite a few instances of this specific problem; we can probably apply the same fix across them all in one go.

To Reproduce
The performance page garbage collection resource count input is a good example of this bug:

Screen.Recording.2024-09-06.at.10.17.36.AM.mov

Expected Result
Old uses of v-model.number need to be replaced with v-model:value.number
