What changed

Translations pulled from Crowdin for 29 languages. The file sharing screens are translated for the first time in all of them, the connectivity screen gains translated status and widget labels, and the Polish "payment pending" label was reworded.

Technical Context

• module_files_action_open ("Open") came back as an adjective or past participle ("opened", "is open") in nine languages, which reads wrong on a button. Dropped in es, it, ja and pt-BR so those fall back to English; left in place but recorded for fi, hu, nb, sv and sr. The underlying cause is the bare source string: it needs context on Crowdin marking it as an action verb.
• Hungarian module_files_quota_low_banner_message had a bare % where the source has %%. That throws a format exception when the low-quota banner renders, so it is the one change here worth a close look. Corrected in both plural forms.
• Serbian module_connectivity_detail_gateway_label and Greek module_meta_detail_device_type_tablet were reverted: the first was an invented term rather than the standard networking word, the second was the untranslated English "Tablet". The Greek revert restored the file to its committed state, so modules-meta does not appear in this diff.
• All of the above are local corrections. The same values are still live on Crowdin and will come back on the next pull unless they are cleaned up there.
