[PATCH proxmox-backup v1] add default pgettext/npgettext implementations to index.hbs

[Kefu Chai <k.chai@proxmox.com>]

From: Kefu Chai <tchaikov@gmail.com>

This adds default implementations for pgettext() and npgettext() functions
to prevent UI breakage when no language is selected.

These functions are required for context-aware translations support added
to the proxmox-i18n tooling.

Default implementations:
- pgettext(context, message): Returns message (ignores context)
- npgettext(context, singular, plural, count): Returns appropriate form

When a language file is loaded, these defaults are replaced by the actual
translation functions from the i18n catalog.
