Open registration let anyone with the URL create an account. Two
changes address that:
- REGISTRATION_CODE (.env, optional): when set, registration requires
entering it correctly. Empty/unset keeps registration open, so
existing installs are unaffected until configured.
- is_admin flag on User: the first account ever created on an install
becomes admin automatically (existing installs get their oldest
account promoted via the startup migration, so nobody is locked
out of user management after upgrading).
Admins get a new "Benutzerverwaltung" panel in Einstellungen listing
every account (email, link/prompt counts, join date) with a delete
button per account — deleting cascades to that user's links and
prompts via the existing relationship cascade. Deleting your own
account through this page is blocked (redirects with an error) to
avoid accidental admin lockout. Non-admins get a 403 on the
/settings/users routes.
Also fixes several pre-existing German pluralization bugs found while
writing the new counts ("2 Linke" -> "2 Links", "Kontoen"/"Konton" ->
"Konten") — irregular plurals need a full word swap, not a suffix.

New /prompts section extends the existing database (new Prompt model,
same SQLite file) and mirrors the Links experience: add a prompt, get
it auto-categorized and tagged by AI, filter by category, full-text
search, sort, edit, or have the AI re-categorize it. A header nav
switch ("Links" / "Prompts") toggles between the two collections; the
shared topbar/menu markup was factored into _topbar.html and
_topbar_actions.html so both pages (and settings) stay in sync.
Each prompt card has a dedicated copy-to-clipboard icon next to
edit/delete, so a stored prompt can be reused immediately. Copying
uses the raw markdown source (not the rendered HTML) so structure
survives when pasted into another AI tool. The copy handler tries the
async Clipboard API first and falls back to a hidden-textarea +
execCommand('copy') for plain-http/non-secure contexts, with clear
success/failure icon feedback either way.
Prompt content supports Markdown and is rendered server-side
(app/mdrender.py) for the card preview. Since this is user-supplied
HTML-adjacent content, rendering goes through two defenses: the raw
text is escaped (only '<' and '&', not '>', so blockquotes keep
working) before conversion so no raw tag can survive, and the
resulting HTML is passed through bleach with a tag/attribute/protocol
allowlist so Markdown-generated links can't carry a javascript: URL.
Verified against raw <script>, <img onerror>, and javascript: link
payloads. The edit form always shows the raw Markdown source, never
the rendered HTML.
Also bumps the default APP_VERSION (shown in the footer) from 1.0.0
to 2.0.0 to mark this feature addition.

New /settings page (linked from the header's burger menu) offers:
- CSV export of the user's links, for spreadsheet apps.
- SQL dump export as INSERT INTO links (...) statements, scoped to
the current user only — never a raw full-database dump, since that
would leak other accounts' password hashes and data. Embeddings are
excluded (regenerated via "KI neu beschreiben lassen" if needed).
- SQL import that re-adds a previously exported dump to the current
account (additive, doesn't touch existing links).
Import safety (app/backup.py): uploaded SQL is never executed against
the real database. Each non-comment line is required to start with
"insert into links" and is run one statement at a time against an
isolated in-memory SQLite database with only a whitelisted `links`
schema (no id/user_id columns) — sqlite3.execute() also rejects
multiple statements per call. Only after that succeeds are rows
copied into the real DB via the ORM, with user_id forced to the
logged-in user. Verified this rejects DROP TABLE, ATTACH DATABASE,
stacked statements, cross-table subqueries, and user_id injection.
Upload is capped at 2 MB.
Also adds download/upload icons and a proper file-input styling
pattern (visually-hidden input + <label> trigger + filename readout),
since the browser's ::file-selector-button pseudo-element didn't
render reliably in testing.
