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)
+
+## [02.58.00] --- 2026-07-06
+
+### Added
+- SFTP destinations: **upload an SSH private key file** in the Add/Edit Destination modal instead of pasting it (reads the file into the key field client-side; pasting still works).
+
+### Changed
+- Add/Edit Destination modal: wrap the content in a Bootstrap `.container-fluid` and give it a 1rem padding frame via the WAM stylesheet (Bootstrap's `.modal-content` has no padding of its own).
+
+### Fixed
+- Pre-update backup now shows an admin notification on **every** outcome (success / warning / failure) — previously a *successful* pre-update backup fired nothing, so it looked like the notification wasn't working. (#192)
+
+### Changed
+- Component admin CSS now loads via the Joomla **Web Asset Manager** (`media/com_mokosuitebackup/` + `joomla.asset.json`) instead of an inline `<style>` block.
+- "Keep local copy" is configured **per remote destination** (in the Add/Edit Destination modal); the redundant profile-level field and its "Remote" tab are removed.
+- Add/Edit Destination modal: cleaned up the cramped padding/margins.
+
+### Fixed
+- Admin menu / duplicate-component fallout: (a) the orphaned `com_component-mokosuitebackup` is now removed in **preflight** too, so its "Backup" menu no longer collides on install ("The alias backup is already being used"); (b) `ensureSubmenuItems()` **recreates the top-level "Backup" menu** if it was deleted, instead of giving up — so Backup no longer disappears from the admin menu (and the cPanel module / MokoSuiteClient can find it again); (c) the component menu label now uses the short constant `COM_MOKOJOOMBACKUP_SHORT`. (#213 fallout)
+- Installer no longer aborts on MySQL 8 with "This command is not supported in the prepared statement protocol yet" (error 1295). The legacy remote-column purge migration (`02.56.01.sql`) used `PREPARE`/`EXECUTE`/`DEALLOCATE`, which Joomla's installer rejects; the drop now runs in the package installer script via an INFORMATION_SCHEMA-gated plain `ALTER` (portable across MariaDB and MySQL 8). (#213 update path)
