Report new articles count per feed in actualize_script output (#8948)

* feat: report new articles count per feed in actualize_script output

Closes #8291

## Changes proposed in this pull request

`app/actualize_script.php` now reports, for each feed that received new articles, how many new articles were fetched — in addition to the existing per-user summary. This makes batch refreshes (cron / systemd timers) much more informative.

Example output:

```
FreshRSS actualize admin…
	10 new article(s) from feed: FreshRSS releases
	3 new article(s) from feed: Some other blog
```

The feature is implemented **entirely within the CLI script**, reusing the existing extension-hook mechanism that the script already uses for the actualization mutex — no change to `feedController` or to any other behaviour:

- `FeedBeforeActualize` records each feed's name.
- `EntryBeforeAdd` counts new entries per feed. This hook fires only in the "genuinely new GUID" branch of the actualization loop (updated articles go through `EntryBeforeUpdate`), so the count matches the controller's own `$nbNewArticles` counter. Because the counting hook is registered after `$app->init()`, it runs last in the chain and is skipped for entries dropped by another extension — i.e. it counts only articles that are actually added.

Counts are printed through the script's existing `notice()` helper, so they reach STDOUT regardless of the `environment` setting (unlike `Minz_Log::notice`, which is suppressed in `production`).

* Minor

* Remove tab
The tab character is escaped in some logs, e.g.

```
 [notice] --- \x091 new article(s) from feed: L’Express
```

* Sort per-feed output and also report updated articles

Addresses review feedback on #8948:
- Sort the per-feed report by descending article count, then feed name.
- Also count updated articles (via EntryBeforeUpdate) and report them
  alongside new ones, e.g. '10 new, 2 updated article(s) from feed: X'.
  EntryBeforeAdd fires only for new articles (new-GUID branch), so
  updated articles need the separate EntryBeforeUpdate hook.

* Reduced code

* Do not report feeds with no new or updated articles

FeedBeforeActualize initializes every actualized feed in $feedStatistics
and fires before the TTL/mute skips, so skipped or unchanged feeds would
otherwise print an empty count ('  article(s) from feed: X'). Skip them.

* Minor code logic preference
