Expand TiFlash monitoring doc by adding many new metrics and sections across the Grafana dashboards. Clarifies that TiFlash proxy/raft metrics overlap heavily with TiKV. Added/renamed entries (e.g. Read Index OPS -> Raft Read Index OPS, Wait Index Duration -> Raft Wait Index Duration) and introduced Write & Delta Management Total. New sections include Imbalance read/write, Memory trace, Storage Read Pool & Data Sharing, PageStorage, Rate Limiter, Raft Snapshot / IngestSST, Disaggregated-Write/Compute, S3, Pipeline Model, TiFlash Resource Control, Status Server, Vector Search, and extensive expansions to TiFlash-Proxy-Summary and TiFlash-Proxy-Details (cluster, errors, server, thread CPU, PD, raft IO/process/message/propose/admin, unified read pool, storage, scheduler, snapshot, task, threads, RocksDB, encryption, etc.). These additions improve coverage and clarity for TiFlash cluster monitoring.

First-time contributors' checklist
What is changed, added or deleted? (Required)
Which TiDB version(s) do your changes apply to? (Required)
Tips for choosing the affected version(s):
By default, CHOOSE MASTER ONLY so your changes will be applied to the next TiDB major or minor releases. If your PR involves a product feature behavior change or a compatibility change, CHOOSE THE AFFECTED RELEASE BRANCH(ES) AND MASTER.
For details, see tips for choosing the affected versions (in Chinese).
