fix(chart): fix label and description translation on UI and enhance french translations

[AliGouta]

SUMMARY

This PR should fix the translation to other languages many static labels and descriptions in the UI.

Fixes SC #40207 Partial UI Translation for Superset Components.

Root cause: Control labels and description(e.g. "Sort ascending") were defined as label: t('...') — strings evaluated at module load time, before the async language pack had finished loading. As a result, Most labels and Description always displayed in English regardless of the selected language.

Fix: Converted to lazy functions: label: () => t('...') — t() is now evaluated at render time, when i18n is already initialized. All controlPanel.ts files across the filter plugins (Select, Range, Time, etc.) were updated accordingly, along with enriched language translations.

@hainenber Kindly trigger the CI if possible. I managed to update the PR. My understanding is that it should be triggered manually if the PR is updated

[AliGouta]

@rusackas Would it be possible to review this PR ? Also, I do not know why the CI does not trigger automatically : s

[rusackas]

I do not know why the CI does not trigger automatically

Just a safety thing, so some rando doesn't come along and do dangerous things with CI.

Once your first PR is merged, it'll be automatic on your second and subsequent PRs.

Reviewing now....

[rusackas]

LGTM!

@AliGouta opened a follow-up PR to this (linked above) if you want to give that a look. Once it's merged, it should be easy to continue sweeping up if needed.
