feat: add Python brace localization format

[Anty0]

Related issue tolgee/tolgee-platform#3589

Summary

• Add the PO_PYTHON_BRACE localization format (Python str.format() / gettext python-brace-format) to push and pull, mirroring the existing PO_PYTHON. It maps to the platform export messageFormat: PYTHON_BRACE and import format PO_PYTHON_BRACE (added to tolgee-platform in #3589).
• schema.json, src/options.ts and src/utils/mapExportFormat.ts updated; src/utils/mapImportFormat.ts needs no change (its default passthrough already forwards the matching PO_PYTHON_BRACE import format).
• Add an e2e round-trip test and PO fixtures: {count:d} (file) ⇄ {count, number} (stored ICU), which exercises the actual converter rather than a placeholder that looks identical in ICU.
• Regenerate the OpenAPI schema (src/client/internal/schema.generated.ts, src/schema.d.ts) against tolgee-platform main; this adds PYTHON_BRACE/PO_PYTHON_BRACE and syncs unrelated schema drift accumulated since the last regeneration.

Summary by CodeRabbit

• New Features

  • Introduced support for the PO_PYTHON_BRACE localization format, enabling translation workflows with Python-style brace placeholders for plural handling (e.g., {count:d} syntax).

• Tests

  • Added end-to-end tests validating push/pull operations for the new format with sample translations in English and French.

Walkthrough

Adds PO_PYTHON_BRACE as a new supported localization format. The format enum is extended in schema.json and src/schema.d.ts, the CLI --format option gains the new choice, and mapExportFormat maps it to format: 'PO' with messageFormat: 'PYTHON_BRACE'. English and French fixture .po files and an e2e test are added.

Changes

PO_PYTHON_BRACE Format Support

Layer / File(s)	Summary
Schema, type, and CLI option contract src/schema.d.ts, schema.json, src/options.ts	Adds PO_PYTHON_BRACE to the Format TypeScript union type, the JSON schema format enum, and the FORMAT_OPT CLI choices list.
Format mapping implementation src/utils/mapExportFormat.ts	Adds a switch case that maps PO_PYTHON_BRACE → { format: 'PO', messageFormat: 'PYTHON_BRACE' }.
E2E fixtures and test case test/__fixtures__/differentFormatsProject/po-python-brace.json, test/__fixtures__/differentFormatsProject/po-python-brace/*.po, test/e2e/formats.test.ts	Adds fixture config, English and French .po translation files, and an e2e test verifying push/pull round-trip behavior including the {count:d} → {count} placeholder transformation.

Poem

🐇 A new format hops into the warren today,
PO_PYTHON_BRACE is now here to stay!
The schema enum grows by just one small line,
The switch case maps it — oh, how divine.
Push and pull the .po files with glee,
{count:d} transforms for you and for me! 🎉
