fix(environment-table-autosave)/autosave removes the already added characters in environment table

[sachin-thakur-bruno]

Description

When Auto Save is triggered while the user is actively typing (especially with Auto Save delays below 1000 ms), the cursor jumps back to its previous position.
This interrupts typing and causes newly entered text to be inserted at the wrong location, making it seem like recent input was lost.

JIRA

Problem

EnvironmentVariablesTable uses Formik with initialValues from environment.variables in Redux.

After every autosave, Redux updated environment.variables with a new array reference. Because enableReinitialize was enabled, Formik reset the form while the user was still typing. The form could not distinguish its own save from a real external update.

Fix

• Removed enableReinitialize.
• Added a snapshot tracker to remember values emitted by the form.
• Only reinitialize when environment.variables changes and the new values are not one of the form's own snapshots.
• Snapshots are recorded for autosave, handleSave, and handleSaveAll.

This prevents save echoes from resetting the form while still allowing genuine external updates to reload the form.

Added e2e for the behaviour and tested them before and after the fix. Before the fix tests were failing as autosave was clearing the texts. After the fix working as autosave is not clearing the unsaved text.
