The Arduino WiFiClientSecure allocates 16KB TLS buffers by default,
which exhausts the ESP32-C3's limited heap (~46KB free after WiFi)
during the TLS handshake. This causes KOReader sync to fail silently
or crash on HTTPS servers (including the default sync.koreader.rocks).
Replace WiFiClientSecure/HTTPClient with esp_http_client (ESP-IDF),
which supports configurable buffer sizes. Use 2KB TLS buffers — more
than sufficient for KOSync's tiny JSON payloads (<1KB).
Also:
- Use esp_crt_bundle for proper TLS certificate verification instead
of setInsecure()
- Strip trailing slashes from server URL to prevent double-slash in
API paths
- Add lastHttpCode for diagnostics
- Add heap logging to help debug memory issues

Resolved conflicts in Section.h and Section.cpp:
- Combined includes (vector for LUT cache + optional/string from master)
- Added imageRendering parameter to loadSectionFile declaration
- Kept non-const clearCache (needs to close file handle for LUT cache)
- Kept in-memory LUT cache in loadPageFromSectionFile (replaces master's
per-page LUT seek)

Adds the missing Turkish translation for STR_SHOW_HIDDEN_FILES in
lib/I18n/translations/turkish.yaml.
- Added: STR_SHOW_HIDDEN_FILES: "Gizli Dosyaları Göster"
- Scope: Turkish only (single-key micro-fix)
This follows up the missing-translations callout in #1483.

.SYNOPSIS
Runs clang-format -i on project *.cpp and *.h files.
.DESCRIPTION
Formats all C/C++ source and header files in the repository, excluding
generated, vendored, and build directories (open-x4-sdk, builtinFonts,
hyphenation tries, uzlib, .pio, *.generated.h).
The clang-format binary path is resolved once and cached in
.local/clang-format-fix.local. On first run it checks a default path,
then PATH, then common install locations. Edit the .local file to
override manually.
.PARAMETER g
Format only git-modified files (git diff --name-only HEAD) instead of
the full tree.
.PARAMETER h
Show this help text.

## Summary
**What is the goal of this PR?**
When viewing a page with images and anti-aliasing enabled, the
`imagePageWithAA` path renders the page twice with fast refreshes (blank
image area, then restore). Both passes called `renderStatusBar()`, which
reads the battery percentage live. If the value changed between the two
renders (e.g. 88% -> 87%), the digits would overlap on screen.
Fix: Removed the redundant `renderStatusBar()` from the second BW
render. The status bar is already drawn and displayed in the first pass,
and only the image area needs restoration.

## Summary
- Add CSS `display: none` support to the EPUB rendering pipeline (fixes
#1431)
- Parse `display` property in stylesheets and inline styles, with full
cascade resolution (element, class, element.class, inline)
- Skip hidden elements and all their descendants in
`ChapterHtmlSlimParser`
- Separate display:none check for `<img>` tags (image code path is
independent of the general element handler)
- Flush pending text blocks before placing images to fix layout ordering
(text preceding an image now correctly renders above it)
- Bump CSS cache version to 4 to invalidate stale caches
- Add test EPUB (`test_display_none.epub`) covering class selectors,
element selectors, combined selectors, inline styles, nested hidden
content, hidden images, style priority/override, and realistic use cases
