Klarbild 1.0.0 — first public release

A self-hosted print studio: images at exact physical sizes, sheet layout with
crop marks, tiling, 1:1 PDF. Everything else — image generation, delivery,
share links, mail, Telegram — is an optional module that is off by default.

This is the neutral public twin of a private tool. Compared to that original:

- optional modules behind KLARBILD_MODULES; the default install is print-only
- English interface with German as a full second language (1,038 strings);
  the English sentence is the translation key
- no built-in accounts — first boot creates one admin from ADMIN_USERNAME /
  ADMIN_PASSWORD, or generates a password and logs it once
- delivery and backup targets are generic SFTP/FTPS endpoints, off by default
- English routes, English identifiers, English comments throughout
- two compose files: print-only by default, everything in the full one
- AGPL-3.0, CI (build, tests, type check, secret scan), CONTRIBUTING, SECURITY

124 tests green, type check clean, verified end to end against a live instance.

+-- Only the **recipe** is stored, not the result: the sheet settings, the
+-- references to the source images, and a few key figures. An A3 print sheet
+-- as a PDF is quickly 20–80 MB; a few dozen prints would fill the disk, and
+-- with files that can be regenerated in seconds at that. The sheet is simply
+-- recomputed on reprint — deterministic, from the same sources.
+--
+-- Row size: roughly 1–3 KB per entry. A thousand prints therefore cost a few
+-- megabytes instead of many gigabytes.
