Sniper scope zoom-in effects should be parity

Description

When zooming in with a scoped weapon (SRS/ZR68L/M41L) in OGNT, there are currently two visual effects that are not parity, as described in the repro steps.

To Reproduce

• Scope in with the SRS (or other sniper; host_timescale can be used to slow down the animation)

Expected behavior

These were tested with the SRS.

• 1.) Before entering the zoomed-in scope view, expecting the viewmodel scope to be raised towards the camera for about 0.1 seconds (or 6 frames of a 60 fps recording).

• 2.) The FOV zoom-in happens instantly for the scope (after the 0.1 seconds vm move).

• 3.) The FOV zoom-out happens instantly (including for a quick-switch to a different gun whilst scoped in).

• 4.) The SRS muzzle flash is not visible from within the scope.

Actual behavior

• 1.) The scope is entered instantly.

• 2.) The FOV zoom-in is lerped like with the un-scoped weapons.

• 3.) The FOV zoom-out is also lerped.

• 4.) The SRS muzzle flash is visible from within the scope.

Additional context and Screenshots

• Additionally, in OGNT, the hip-fire crosshair makes a brief appearance in the 0.1 seconds transition state of the vm scope moving but before we've entered the scope. We don't currently do this. But I imagine we might not want to replicate this one, since we already offer the hip-fire crosshair as an accessibility feature which should cover any use-cases for this pre-scope crosshair to line up shots etc.
