Nick Craig-Wood 930de88f69 protondrive: fix files uploaded with v1.75.0 not being readable in the Proton apps
rclone v1.75.0 started creating files in Proton Drive's new
crypto-refresh encryption format, following guidance from Proton that
new file node keys should use the v6/AEAD profile. It turns out the
official Proton web app cannot decrypt files whose node key is a v6
key (but the Android app can), so every file uploaded with v1.75.0 (or
a beta after 2026-07-13) shows 'Item cannot be decrypted' in the web
app, even though rclone itself reads the files fine. Inspecting a file
created by the web app shows Proton itself still creates v4 node keys,
using the new format only for the file content.

New files are now created with the same fully pre-crypto-refresh
format as v1.74.4 (v4 node key, v3 PKESK content key, v1 SEIPD
blocks), which every Proton client can read. Reading files in the new
format still works, new revisions of files which already use the new
content format keep it, and the auxiliary fields (name, node
passphrase, extended attributes, block signatures) are pinned to the
old format regardless of the recipient key's preferences, as Proton
requires.

Files already uploaded with v1.75.0 cannot be repaired in place -
uploading a new revision does not change the file's node key. To make
such a file readable by the Proton apps again, delete it from the
remote and upload it again with a fixed version of rclone.

This updates Proton-API-Bridge to v1.0.5 and go-proton-api to v1.0.4.
