Follow-up to the 64k bump: raised bot-block-proxy large_client_header_buffers
to 256k and corrected the rationale. Investigation found the *binding* limit
for browsers is Traefik's HTTP/2 header cap (~64KB, Go maxHeaderListSize, not
exposed by Traefik config) — oversized authentik_proxy_* cookie piles are
rejected at the h2 layer upstream of bot-block regardless of these buffers.
The real fix for >64KB piles is reducing authentik_proxy_* cookie accumulation
(or clearing cookies); these buffers only prevent bot-block being a tighter
bottleneck for sub-64KB piles + HTTP/1.1 clients.
