Complete Portuguese (pt) UI translation to 90%+ coverage

[andreahlert]

Summary

Complete the Portuguese (pt) locale translation for the Airflow UI. Coverage is currently 85.8%; target is 90% per i18n policy.

Context

• The pt locale was added in [RFC] Feat(ui): Add portuguese translation + CODEOWNER #52341 (2025-09-11). The 112 missing keys were added to the English locale *after* that merge (new features: Jobs page, XCom UI, diff view, partition keys, etc.), so they were never translated.
• This PR will add the missing keys and align/remove the 11 extra keys reported by breeze ui check-translation-completeness --language pt.

Plan

• Add missing keys across admin.json, assets.json, browse.json, common.json, components.json, dag.json, dags.json, dashboard.json, hitl.json
• Remove or align extra keys (e.g. pools in common.json, hitl filters) per en locale
• Run breeze ui check-translation-completeness --language pt and confirm ≥90%

Checklist

• Translation follows pt (Portugal) conventions; terminology consistent with existing pt strings
• No new keys in en were introduced in this PR (only pt files changed)

Related: #62001 (translation agent skill guidelines for pt).

Was generative AI tooling used to co-author this PR?

• Yes - Cursor, for reviewing if all keys were covered.

Hi @aoelvp94 @victoru2 @potiuk,

I only added the new missing keys to complete the pt locale.

The current locale is pt (Portugal). Would it be okay if I added a pt-BR variant?

I’m Brazilian, by the way. If any other PMC member or committer is Brazilian and wants to be involved (e.g. as translation owner or reviewer), I’d be glad to coordinate with them.

Context: Brazil is in the top 8 countries for Airflow adoption (TheirStack), with ~637 companies and an estimated 2k–5k active users (e.g. iFood, Nubank, Magalu, Itaú). Among current committers who set a location on GitHub, I guess none are in Brazil, so there’s strong adoption and little representation.

A pt-BR variant would serve that base without changing the existing pt locale.

WDYT?

Thanks.

WDYT?

Absolutely.

Maybe @tatiana can help with reviews ?

Absolutely.

Thanks, @potiuk. I’ll follow the process and then open a follow-up PR to add the pt-BR variant.

@tatiana será um prazer e obrigado pela ajuda!
