Closes#3789, #6503
Icon setting when no custom icon is set yet:

- `Change...` button opens a file dialog, and after selecting a file shows the chosen icon in the preview on the left. `Submit` must be clicked after selecting the icon.
- `Reset to default` changes the preview icon to the default one, and also requires `Submit` to be clicked to apply the changes.
Full list of changes:
- CSP now includes `blob:` in `img-src` for
- `indexAction()` and `feedAction()` in `subscriptionController.php`
- all of the view actions in `indexController.php`
- Introduce new attribute `customFavicon (boolean)` for feeds that indicates if the feed has a custom favicon
- `hashFavicon()` in `Feed.php` is dependent on this attribute
- `hashFavicon()` has a new parameter called `skipCache (boolean)` that allows the reset of the favicon hash for the Feed object
- `resetFaviconHash()` just calls `hashFavicon(skipCache: true)`
- `f.php` URLs now have the format of `/f.php?h=XXXXX&t=cachebuster`, where the `t` parameter is only used for serving custom favicons
- if `t` parameter is set, `f.php` returns a `Cache-Control: immutable` header
- `stripos` and `strpos` were changed to `str_contains` in various places (refactor)
- JS for handling the custom favicon configuration logic is in `extra.js` inside `init_update_feed()` which is called when feed configuration is opened from the aside or when the subscription management page with the feed is loaded
- Server-side code for uploading the icon in `subscriptionController.php` under `feedAction()`
- Errors that may occur during the setting of a custom favicon:
- Unsupported image file type (handled only server-side with `isImgMime()`)
- When the file is bigger than 1 MiB (default), handled both client-side and server-side
- Standard feed error when `updateFeed()` fails
- JS vars `javascript_vars.phtml` are no longer escaped with `htmlspecialchars()`, instead with json encoding,
- CSS for disabled buttons was added
- Max favicon file size is configurable with the `max_favicon_upload_size` option in `config.php` (not exposed via UI)
- Custom favicons are currently deleted only when they are either reset to the default icon, or the feed gets deleted. They do not get deleted when the user deletes their account without removing their feeds first.
- ` faviconPrepare()` and `faviconRebuild()` are not allowed to be called when the `customFavicon` attribute is `true`
- New i18n strings:
- `'sub.feed.icon' => 'Icon'`
- `'sub.feed.change_favicon' => 'Change…'`
- `'sub.feed.reset_favicon' => 'Reset to default'`
- `'sub.feed.favicon_changed_by_ext' => 'The icon has been set by the <b>%s</b> extension.'`
- `'feedback.sub.feed.favicon.too_large' => 'Uploaded icon is too large. The maximum file size is <em>%s</em>.'`
- `'feedback.sub.feed.favicon.unsupported_format' => 'Unsupported image file format!'`
- Extension hook `custom_favicon_hash`
- `setCustomFavicon()` method
- `resetCustomFavicon()` method
- `customFaviconExt` and `customFaviconDisallowDel` attributes
- example of usage: https://github.com/FreshRSS/Extensions/pull/337
- Extension hook `custom_favicon_btn_url`
- Allows extensions to implement a button for setting a custom favicon for individual feeds by providing an URL. The URL will be sent a POST request with the `extAction` field set to either `query_icon_info` or `update_icon`, along with an `id` field which describes the feed's ID.
* + Exposed the reading modes for extensions through Minz. Now extensions can add a custom view mode. Graceful fallback to normal view in case the extension was disabled without resetting the view_mode through the uninstall method. In that case the user will be informed via Minz_Request::setBadNotification that the view has been reset to normal.
+ Added translation strings for de, en and en-us for the notification
* + Added missing, generated translations
* Simplify indexAction, performance
* Minor settings htmlspecialchars
* i18n: fr
* Minor wording
* Doc
* Fix i18n

* Fix encoding of themes
Several HTML and URL encoding issues in the case of special chars in theme directory or in metadata.
Also usefull to simplify https://github.com/FreshRSS/FreshRSS/pull/7559
* Minor simplification

* Fix typing
* Hash of Web site in priority for favicons
* Continue
* Revert some minor changes

MINZ (archived, read-only) is not a dependency
of FreshRSS, which would be very concerning.
Instead, FreshRSS copied MINZ and has evolved
it since then under the same license.

Fix issue where $keepMax is defaulted to const when non-zero value is compared.
Fix an issue where $keepMax var is set to ARCHIVING_RETENTION_COUNT_LIMIT
when a user sets "Archiving" -> "Maximum number of articles to keep per
feed" to a non-zero value for a given category.
[EXAMPLE]:
User sets value to 50 (int), This matches the !== comparison and
thus is overridden by ARCHIVING_RETENTION_COUNT_LIMIT.
