Fix terminal uploads, note persistence feedback, and GUI regressions

[bifrost0x]

Changes

Fix the terminal drop flow so files are queued only after confirming the destination. A single handler receives the real session manager, captures the active target at drop time, and keeps that target if the user switches sessions. The dialog shows the server and destination folder; relative paths explicitly refer to the SFTP home directory. Disconnected targets fail instead of falling back to another session.

• Read every directory-entry batch and await the matching directory-creation response before uploading children. Stop on creation failure, disconnect, or timeout.
• Show notes as saved only after a successful server acknowledgement. Preserve dirty text across reconnects and late responses, serialize pending saves, report failures/offline state, enforce the character limit, and warn before leaving with unsaved notes.
• Accept IPv6 and IDN hosts in Quick Connect hints, align dotted usernames with the existing backend policy, and localize validation/status text in all six locales.
• Constrain the settings navigation grid and wrap translated labels so the German sidebar no longer overlaps content at intermediate widths.

Validation

• 2,826 Python tests passed across the full suite and a separate socket-capacity run; 29 skipped. The capacity test required local socket permissions unavailable in the initial sandbox run.
• All 43 JavaScript test files passed; ESLint and git diff --check passed.
• 22 browser tests passed, covering the new regressions and existing Quick Connect, File Manager, and account-menu flows.
• Directory tests cover 200 entries across multiple batches, response correlation, failure cleanup, cancellation, and target binding. Browser tests verify real note persistence/reconnect and sidebar bounds at 601, 768, 900, and 1024 pixels.

Browser checks used the isolated E2E instance. SSH targets and transfers in the drop regression were simulated; no external SSH/SFTP/SMB server was contacted.
