Abort query when the SSH client disconnects

SSH change queries can spend significant time building output for each
matching change, especially when options such as patch sets, approvals,
or submit records are enabled. If the client disconnects before the
query finishes, the server should stop work promptly instead of
continuing to process results that will never be sent.

Release-Notes: skip

Speed up bloom filter build with OS page cache warmup

Loading bloom filters at startup requires a full table scan of every H2
cache file. Without warm OS page caches these reads are I/O-bound,
making startup significantly slower.This change performs a full read of
the H2 file before building the Bloom filters, ensuring that the OS page
cache is populated.

On a production instance with ~84M disk cache entries combined, this
reduced the load up time from ~22 mins to ~16 mins.

Release-Notes: Add file warming for faster H2 bloom filter building.

Route fix:preview REST API requests through readScheduler

POST /fix:preview is a read-only diff generation request, but because
it uses HttpMethod.POST, GrRestApiHelper was classifying it as a write
operation and routing it to writeScheduler. High volumes of fix:preview
requests could saturate writeScheduler and delay write requests like
saving comment drafts or sending replies.

Add a useReadScheduler flag to FetchRequest and set it for fix:preview
requests so they are routed through readScheduler.

Release-Notes: Route POST /fix:preview requests through readScheduler

H2Cache: Warm up OS page cache before collecting disk stats

diskStats() scans disk entries for size and space accounting. Apply
the same OS page cache warmup used during bloom filter builds to avoid
cold-read latency when collecting these stats.

Release-Notes: querying disk stats on large persistent caches is improved
