i18n: translate the Filename Templates feature into all locales

26 keys (settings.filenameTemplates.*, filenameTemplateProgress,
modals.filenameTemplateConfirm, related toasts) translated into the 9
non-English locales, reusing each locale's autoOrganizeProgress /
downloadPathTemplates renderings. Terminology recorded in

+    small and add the bulk via `extra_folder_paths`.

+# Plan: Filename Template Follow-ups
+
+**Issue:** [#1071 — Lora Renaming](https://github.com/willmiao/ComfyUI-Lora-Manager/issues/1071)
+**Status:** Core feature **implemented** (2026-09-19, commit `2bc9860b`,
+preceded by the settings-tab split in `327da046`). Follow-ups 1 and 2 were
+resolved together on 2026-09-19 by redefining the empty template as
+"revert to recorded original filename" (see below). Follow-up 3 remains open.
+
+## What shipped in `2bc9860b`
+
+- Per-model-type `download_filename_templates` setting (empty = keep current
+  filename; opt-in). Placeholders: `{model_name}`, `{version_name}`,
+  `{base_model}`, `{author}`, `{first_tag}`, `{hash_short}`,
+  `{original_name}`.
+- `calculate_filename_for_model()` in `py/utils/utils.py` renders the
+  template; templates containing path separators are rejected.
+- Downloads apply the template post-download
+  (`DownloadManager._apply_download_filename_template`); rename conflicts
+  keep the original name and never fail the download.
+- `ModelLifecycleService.rename_model` records `original_file_name` in the
+  `.metadata.json` sidecar (first rename wins via `setdefault`).
+- Bulk apply: `GET|POST /api/lm/{prefix}/apply-filename-template`
+  (`FilenameTemplateUseCase`, shares the auto-organize lock, WS progress type
+  `filename_template_progress`).
+- Settings UI: "Filename Templates" subsection in the new **Organization**
+  settings tab (`templates/components/modals/settings/organization.html`),
+  with validation, live preview, and per-type "Apply to Library Now".
+
+Sandbox E2E verified: rename incl. companion files (previews, sidecars),
+metadata pointer updates, `original_file_name` recording, idempotency,
+conflict handling (failure counted, batch continues), empty-template no-op,
+GET variant.
+
+## Follow-ups 1 & 2 — RESOLVED: empty template = revert to recorded original
+
+Follow-up 1 asked to reword the ambiguous "Valid (keep original filename)"
+empty-template message; Follow-up 2 asked for a bulk revert to the recorded
+`original_file_name`. Both were resolved by a single semantic change: **an
+empty template now means "restore the recorded original filename"** instead of
+"leave the current filename untouched".
+
+Rationale: for never-renamed models a revert is a no-op (no recorded
+original), for renamed models it restores the pre-rename name, and new
+downloads with an empty template keep the download name as before — so the
+two contexts (download path and bulk apply) share one coherent meaning, and
+no separate revert feature or `{recorded_original}` placeholder is needed.
+
+Implemented changes:
+
+- `FilenameTemplateUseCase._process_model`: an empty template now resolves
+  the target name from the sidecar's `original_file_name` via the injected
+  `metadata_loader` (default `load_local_metadata`); models without a
+  recorded original or whose original matches the current name are skipped.
+  Cache entries do not project `original_file_name`, so the sidecar is read
+  per model.
+- `SettingsManager.js`: removed the empty-template early return and the
+  apply-button disable (`updateFilenameTemplateApplyButton` deleted — the
+  button is now always enabled). The browser-native `confirm()` was replaced
+  with `filenameTemplateConfirmModal`
+  (`templates/components/modals/confirm_modals.html`), a **self-managed**
+  modal (like `DirectoryPickerModal`, NOT registered with ModalManager):
+  ModalManager's "close current modal on open" behavior would kill the
+  settings modal underneath. It stacks via `z-index: 10010`
+  (`delete-modal.css`), handles ESC in capture phase with
+  `stopPropagation`, and shows apply vs revert wording
+  (`modals.filenameTemplateConfirm.titleApply` / `titleRevert` /
+  `revertButton`; messages reuse `settings.filenameTemplates.confirmApply` /
+  `confirmRevert`).
+- `locales/en.json`: reworded `help` / `applyHelp`, replaced
+  `validation.keepOriginal` with `validation.restoreOriginal`
+  ("Valid (empty template restores original filenames)"), added
+  `confirmRevert`, removed the now-unused `emptyTemplateInfo`. Other locales
+  re-synced with `[TODO: Translate]` placeholders — retranslation waits for
+  the feature owner's request per `docs/i18n-translation-guidelines.md` §7.
+- Tests: revert / no-record-skip / same-name-skip cases in
+  `tests/services/test_use_cases.py`; modal confirm-and-revert and
+  cancel paths in
+  `tests/frontend/managers/settingsManager.filenameTemplates.test.js`.
+
+Sandbox E2E verified (standalone server, sandboxed settings + library under
+`/tmp`, 2026-09-19): template apply renames and records
+`original_file_name`; empty-template apply reverts to the recorded name;
+revert target occupied by a newer file counts as failure and keeps the
+current name; models without a recorded original are skipped;
+apply → revert → re-apply cycles repeat cleanly.
+
+Standing caveats (unchanged):
+
+- The revert target may collide with an existing file — the existing conflict
+  handling (count as failure, keep current name) covers this.
+- `original_file_name` only exists for models renamed after `2bc9860b`;
+  older renames have no recorded original and are skipped.
+- `original_file_name` is kept (not cleared) after a revert, so
+  apply → revert → re-apply stays repeatable.
+
+## Follow-up 3 — Cross-page refresh after bulk apply
+
+**Problem:** the settings-modal "Apply to Library Now" button calls
+`resetAndReload(true)`, which refreshes only the page type currently open.
+Applying the checkpoint template while on the loras page leaves the loras
+view refreshed but does not touch the checkpoints page state (same
+limitation as the existing bulk auto-organize flow in
+`static/js/managers/SettingsManager.js#applyFilenameTemplate`).
+
+**Fix options:** broadcast a generic "library changed" event that every
+page's state listens to, or accept the limitation (the other page reloads
+its cache on next visit). Low priority.
