Disable unread counter in tab title and favicon (refresh of #6590) (#8728)

Closes FreshRSS/FreshRSS#6522.

Refresh of FreshRSS/FreshRSS#6590 by @sgzmd, which has been stalled with merge
conflicts since 2024. All original commits are preserved as-is in the history
(authorship intact); this PR adds a merge with current `edge` plus minor fixes.

## Summary

Adds a user setting `show_title_unread` (default `true`, so existing behavior
is preserved) that hides the unread article counter from both the tab title
and the favicon overlay. A single toggle controls both, matching the request
in #6522.

## Screenshots

Toggle in display settings:

Tab title and favicon when **enabled** (current behavior):

## Changes on top of #6590

- Resolved merge conflicts with current `edge` (controllers, model, view,
  `config.default.php`, ~25 i18n files, plus the `zh-tw` -> `zh-TW` rename).
- Replaced Czech text mistakenly placed in `de/conf.php` with an English
  `// TODO` marker so a German speaker can translate later.
- Renamed JS context key `show_unread_favicon` -> `show_title_unread` to
  match the backend property and avoid a confusing dual-name for one setting.
- Removed an unused duplicate of `show_title_unread` from `config.default.php`
  (the setting is read via `userConf()`, never `systemConf()`).
- Gated the dynamic title rewrite in `incUnreadsFeed` (`p/scripts/main.js`)
  on the setting. Without this, marking an article read while the setting
  was off would re-add the `(N)` prefix to the tab title.
- Escaped a stray apostrophe in the Occitan translation that broke parsing.
- `make fix-all` re-sorted i18n keys and added `// TODO` placeholders for
  `fi`, `pt-PT`, `uk` (untranslated by the original PR).

## Test plan

- [x] `make test-all` passes (620/620 PHPUnit, phpstan, phpcs, eslint,
      stylelint, markdownlint clean; `bin/typos` failed locally with a binary
      arch mismatch on macOS arm64 - unrelated to this change).
- [x] Manually tested on a real instance: default behavior unchanged;
      toggling the setting hides both the tab title `(N) ` prefix and the
      favicon overlay; toggling back restores both; marking articles read
      while the setting is off does not bring the counter back; opening and
      closing an article preserves the user's choice.

* Make showing the number of unread items in the title configurable.

* Proposed approach to passing show_unread_favicon setting down to client-side code

* Fixes and refactoring

* Updating default config for the user.

When user's config wasn't initialised we are copying it from `config-user.default.php` - if `show_title_unread` is not there, it is assumed to be false, whereas in `config.default.php` it's true by default. This results in inconsistency until user changes the field for the first time in Config->Display.

* Adding translations.

* fix: gate JS title rewrite + drop dead system config entry

The original PR added show_title_unread to both config-user.default.php
(read by userConf, the right place) and config.default.php (read by
systemConf, never used here). Drop the system-level entry.

Also: incUnreadsFeed dynamically rewrites document.title when articles
are marked read/unread. That code path was not gated by the setting, so
toggling the setting off and then marking an article read would re-add
the (N) prefix to the tab title. Skip the document.title / prevTitle
write when context.show_title_unread is false.

* fix: drop README pollution from local make fix-all

`make fix-all` regenerated the README translation tables on macOS, where the
case-insensitive filesystem and an untracked local `app/i18n/nb/` directory
caused the generator to emit `zh-tw` (lowercase) and an `nb` entry. Reset
both README files to upstream/edge so CI can regenerate them cleanly.

* fix: restore zh-TW/conf.php from edge (case-insensitive FS damage)

The macOS case-insensitive filesystem caused the merge to overwrite
upstream/edge's properly-translated zh-TW/conf.php with the older
zh-tw/conf.php content from the PR side, regressing translation
coverage from 94% to 71%. Reset the file to edge's content and re-add
the show_title_unread Traditional Chinese translation.
