Add tooltip format for Hyprland language

[xtakenotesx16]

Summary

• Add tooltip-format support to hyprland/language
• Format tooltip text with the same layout placeholders used by format
• Document the new option in the Hyprland language man page

Problem

hyprland/language can format the visible label with {long}, {short}, {shortDescription}, and {variant}, but there is no separate tooltip format. This addresses #3693.

Fix

The module now reads tooltip-format from config and applies it on update when tooltips are enabled. If tooltip-format is not configured, the tooltip falls back to the displayed label text, matching the behavior used by similar language modules.

Verification:

• Ran git diff --check.
• Full build was not run locally because the workspace does not have Meson/Ninja/C++ build dependencies.
• Runtime Hyprland check was not run locally because the workspace does not have a Hyprland session.

Risk

Low. The change is limited to hyprland/language tooltip rendering and documentation. Existing label formatting is unchanged.
