Botty+ 1.4.5 — Optional A53 PPR patch

Adds the optional A53 PPR game compatibility patch to Launch options. It is unchecked by default, saved per browser, and disabled above PS5 firmware 11.40. The launcher sends the standard a53_ppr_install.elf after Kstuff and waits for the user to confirm the successful notification before loading ShadowMountPlus. Close games and wait for mounts and unmounts to finish before using it.

The payload is built from pinned, unmodified drakmor/ppr-patch sources with SDK v0.43 on the VPS. Its GPL license, complete corresponding source and provenance are included in the verified portal archive. Existing application and service versions are preserved.

Validation: portal Node tests (including default-off, firmware guard, saved choices and launch ordering), nine Python export/source regressions, upstream PPR state-machine host tests, public hashes and installer pins. UI inspected in the browser. Deployed to the portal; PPR console acceptance is pending.
