chore(version): pre-release bump to 02.58.14-dev [skip ci]

The pre-update return URL is assigned to window.location.href, so a
javascript:/data: URI (empty host) would have passed the host-only check
and executed. Require an absolute http(s) same-host URL or a single-slash
root-relative path; reject javascript:/data:/vbscript: and protocol-relative
//host.

 ## [Unreleased]
 
+### Added
+- **Full-screen backup screen** (`view=runbackup`) for both pre-update and manual backups, modelled on Akeeba's Backup-on-Update — replaces the earlier popup-modal approach. Clicking Joomla's **Install the update** now redirects (server-side, Akeeba-style) to a dedicated full-page backup screen that runs the stepped backup with a real progress bar and then **automatically continues the update** via a validated `returnurl` (flagged `is_backed_up=1` so the backup isn't repeated). Crucially, **no backup runs synchronously inside the update request** — which is what white-screened large sites. The dashboard **Backup Now** now opens the same full-screen screen instead of an inline modal. (#196)
+- Retention now prunes **remote** copies too: when a backup is pruned by age/count, its archive is deleted from every enabled remote destination (SFTP / FTP / S3 / Google Drive), not just the local copy. Each uploader gained an idempotent `delete()` method (already-absent file = success), and removal is best-effort — a failing destination is logged but never blocks local pruning. The shared standalone `restore.php` is intentionally left in place (every backup overwrites it, so newer backups still depend on it). (#229)
+
+### Changed
+- Consolidated backup plumbing into shared helpers (#230):
+  - New `RemoteUploaderFactory` replaces the `createUploaderFromParams()` copy that was duplicated in `BackupEngine` and `SteppedBackupEngine`.
+  - `RetentionManager` is now the single retention authority — it takes the global `max_age_days`/`max_backups` fallback and gained `pruneOrphans()`; the system plugin's hourly cleanup delegates to it and its duplicate `deleteBackupRecord()` logic is removed.
+  - The backend controller, Web Services API controller, and legacy `cli/mokosuitebackup.php` now run backups through the shared `BackupRunner` (gaining the normalized complete/warning/fail status) instead of instantiating `BackupEngine` directly.
+
 ### Fixed
+- Pre-update/uninstall backup no longer **white-screens** the update on large sites. The synchronous backup that runs inside the extension update/uninstall request now raises `max_execution_time`/`memory_limit` (and `ignore_user_abort`) like the web-cron path, so it can't exhaust the request's default limits mid-backup. (Core Joomla updates additionally get a full-screen backup screen — see below.)
+- Archive names for **CLI/console-triggered backups** no longer come out as `joomla.invalid_…`. The `[HOST]` placeholder took `$_SERVER['HTTP_HOST']` verbatim, but Joomla's console fills that with the reserved sentinel host `joomla.invalid`; the resolver now treats that (like empty/`localhost`) as unusable and falls back to the configured `live_site` host, then the system hostname. (Set the site's *live_site* to get the exact domain in CLI-built names.)
 - Standalone restore script generation no longer aborts backups with `str_replace() expects at least 3 arguments, 2 given`. `MokoRestore::generateStandaloneScript()` had a `str_replace()` call (the "Backup Archive" pre-check rewrite) that was missing its `$php` subject argument, so **every** standalone-mode backup fatally errored while "Generating standalone restore.php…" — the archive still finalized and uploaded, but no `restore.php` was ever produced (the true root cause behind #226). (#226)
 - Remote upload: the standalone restore script upload is no longer silent — its result is now checked and logged, and a failed restore-script upload marks the backup as `warning` (previously the result was discarded, so a missing restore script on the remote went unreported while the archive still showed success). (#226)
