feat: rtl support in helpdesk

[aerodeval]

Overview
Adds full right-to-left (RTL) language support across the Helpdesk UI, ensuring correct layout, spacing, and alignment for RTL locales such as Arabic

Changes

Spacing & Layout
improved ux flow according to RTL flows
Fixed places where positioning was enforced with the correct direction based on on rtl
Replaced space-x-* with gap-* on flex containers — space-x uses margin-left and does not flip in RTL
Replaced border-l / border-r the alternative border properties

Translations
Wrapped all user-facing strings with ()
Replaced template literals with ("{0}", [dynamic]) placeholder syntax for dynamic strings
Fixed label={(...)} JSX syntax to Vue-correct :label="('...')"
