refactor: disable cleanup by default, set ENABLE_CLEANUP=true to activate

fix: add curl to Dockerfile + env wrapper for crond jobs

feat: add automatic token cleanup with crond + fixed /tmp/crontabs for HF read-only fs

revert: restore to 03e51a9 baseline (remove cleanup scripts)

fix: complete solution - entrypoint with /tmp/crontabs + config without pgstore-dsn

test: minimal entrypoint - just echo and exec

fix: make crond non-fatal with sleep-loop fallback

fix: read-only filesystem + remove pgstore-dsn from config

debug: add diagnostic logging to entrypoint

fix: use /tmp/crontabs for read-only root filesystem

fix: wait for API ready before running initial token cleanup

Update entrypoint.sh
