…calls (erigontech#21)

sepolia bindings

* Remove redundant writes when a state object is reverted

* Change IsDirty to Transaction level

We don't want a reverted transaction to show up in written trace because it was touched by a previous transaction.

* Add storage read whenever there is a sstore

This fixes an issue when a storage slot is
* written but got reverted
* never read by sLoad opcode

When this happens, we still need to include the storage slot in the trace.

Apply PR additions: FAQs #21 (pruning/historical blocks) and #22 (ARM/RPi)

## Summary

Ports the full Help Center content to `release/3.4`, mirroring what was
merged to `main` via PR #20267.

Changes per file:

- **best-practices.md**: added "Harden Public RPC Endpoints" row +
Section 6 (Advanced Performance Tricks with vmtouch,
ERIGON_SNAPSHOT_MADV_RND, db.pagesize)
- **common-errors-and-solutions.md**: added errors #8 (Docker UID/GID
mismatch) and #9 (libsilkworm_capi.so missing)
- **frequently-asked-questions-faqs.md**: added FAQ #21 (historical
block queries / pruning) and #22 (ARM/RPi feasibility)
- **known-issues.md**: improved vmmap/pmap section (macOS vs Linux),
removed DOCKER_BUILDKIT env vars, added `--db.pagesize` section (default
16KB)
- **troubleshooting.md**: added Diagnostics section (SIGUSR1 goroutine
dump, pprof CPU/heap capture) and Hetzner firewall note

All content is identical to `main` post-#20267, with yperbasis review
fixes already applied (broken erigon-lib link removed, pprof addr/port
flags documented).

## Test plan

- [ ] Verify all 5 files render correctly in GitBook preview
- [ ] No broken internal links
- [ ] Content consistent with release/3.3 (PR #20263) and main
