Docker: Fix condition of recording by session capability se:recordVideo

[VietND96]

Description

This change ensures that the SE_RECORD_VIDEO environment variable is consistently honored across both event-driven and shell-mode video recording. Previously, when the se:recordVideo capability was absent from a session, the code would default to true regardless of the SE_RECORD_VIDEO environment setting.

The fix implements a fallback mechanism in both video_service.py and video_graphQLQuery.py:

• When se:recordVideo capability is present on the session, it takes precedence
• When the capability is absent (None), the code now falls back to the SE_RECORD_VIDEO environment variable (defaulting to "true" if not set)
• Improved handling of different value types (string, boolean, etc.) with explicit type conversion

This brings consistency with the shell-mode helper (video_nodeQuery.py) and ensures SE_RECORD_VIDEO=false is respected in all recording modes.

Motivation and Context

Users setting SE_RECORD_VIDEO=false to disable video recording would find it ignored when sessions didn't explicitly include the se:recordVideo capability. This inconsistency between event-driven and shell-mode recording behavior could lead to unexpected video files being generated.
