Vinicius Gabriel c53545d9fe Add configurable word separator for naming templates (#1333)
Closes #1230

## What
Adds a "Word Separator" setting (Space / Dot / Underscore / Hyphen /
Custom) that replaces internal whitespace in each naming-template
placeholder's rendered value — e.g. `{Author}` renders
"Arthur.Conan.Doyle" instead of "Arthur Conan Doyle" when Dot is
selected.

This follows option 2 from the issue rather than inventing new
dotted-keyword template syntax (`{Author.}`), since it's a smaller
surface: one setting applies uniformly across all four templates
(books/audiobooks × rename/organize) instead of needing a parallel token
for every existing one.

## How it works
- Literal characters typed into the template itself (e.g. the `.` in
`{Author}.-.{Title}`) are never touched — only whitespace *inside* a
placeholder's resolved value is affected.
- Default is "Space", which is a no-op: existing templates produce
byte-identical output after this change (verified via the existing test
suite, unmodified, still passing).

## Where
- `shelfmark/core/naming.py` — `word_separator` param on
`parse_naming_template` / `build_library_path`.
- `shelfmark/download/postprocess/policy.py` — `get_word_separator()`,
mirroring the existing `get_file_organization()` accessor.
- `shelfmark/download/postprocess/transfer.py` — wires the resolved
separator through the four existing template-rendering call sites.
- `shelfmark/config/settings.py` — new `Word Separator` / `Custom Word
Separator` fields next to the existing naming-template fields.
- `src/frontend/.../namingTemplatePreview.ts` +
`NamingTemplateField.tsx` — the settings UI has its own TS mirror of the
Python renderer for the live preview; updated it in lockstep so the
preview doesn't lie about what the separator will actually do.
- Tests added on both sides (pytest + vitest).

## Testing
- `uv run pytest tests/core/test_naming.py
tests/core/test_destination_file_organization.py` — all pass, including
new cases.
- `uv run pytest` (full suite) — same pre-existing failures as on `main`
before this change (browser/network-dependent bypass & e2e tests
unrelated to this diff), everything else green.
- `uv run ruff check` / `ruff format --check` / `basedpyright` — clean.
- `npm run lint` / `format:check` / `typecheck` / `test:unit` (196
tests) — clean.
