fix(ux): input error messages no longer overlap adjacent fields in forms (#21886)

## Context

`InputErrorHelper` used `position: absolute` which took the error
message out of normal document flow. In multi-field grid layouts (e.g.
the HTTP Request workflow node editor), this caused the error text to
render on top of the input below it instead of pushing it down.

## Solution

Removed `position: absolute` from `InputErrorHelper`. The error message
now participates in normal document flow and pushes subsequent content
downward, as expected in modern forms.

## Test plan

- [x] Open the HTTP Request node editor, fill in a field incorrectly —
error message appears below the field without overlapping the next input
- [x] Verify single-field forms still display error messages correctly
