i18n(ja): fix translation defects in the v6.5.x and v6.6.0 release notes

[yahonda]

What is changed, added or deleted? (Required)

Fixes translation defects in the Japanese release notes for v6.5.0 to v6.6.0 (14 files). This is the second half of round 5 of the releases/ review; v6.0.0-DMR to v6.4.0 are in a separate PR. I checked each item against its EN bullet (release-8.5) and against resources/terms-en-ja.md.

Meaning fixes

• 6.6.0:
  • L496: almost the whole bullet was missing. It is restored from EN.
  • L341: "to replace on-duplicate" was dropped, so all three items read as new.
  • L508: two duplicated "fix" clauses are merged, in the EN order.
  • Swapped identifiers in L56 (LIMIT parameters) and L308 (TTL_JOB_INTERVAL/tidb_ttl_job_run_interval).
  • Scrambled L151, L296, L300, and L348.
• 6.5.0:
  • L272: "bidirectional" was dropped.
  • L344/L347: the enum value MEDIUM was translated.
  • TiKV-BR had a stray space.
• 6.5.6 L108 and 6.5.x: the OOM cause; "store messages" was read as "save"; the Sort spill condition; "the Leader fails to transfer".
• 6.5.4 L142: fsp of DATETIME/TIMESTAMP/TIME.
• A broken handle: [5kb] → @[5kbpers] (6.6.0).
• Wrong-domain words:
  • 拘束 → バインド.
  • 条項 → 句.
  • 感度調整 → 秘匿化.
  • 2人のDDL所有者 → 2つのDDL Owner.
  • 本番 → 生成.
  • 回転 → スピン.
  • 管理者チェックサム → ADMIN CHECKSUM.

Glossary and literals

• Glossary terms:
  • Stale Read → ステイル読み取り.
  • Capitalized Learner and Leader stay in English (lowercase "learner" is ラーナー).
  • privileges → 権限.
  • online unsafe recovery → オンラインアンセーフリカバリ.
  • Region → リージョン.
• These stay in English: Resolved TS, Scatter Region, safe-ts, meta-kv, crossbeam-channel, a Grafana metric name, and @[hi-rustin] (as in EN).

Particles and Markdown

• Restores particles dropped after links or backticks (about 60 sites); removes stray particles and full stops, and backticks inside issue-link text.

Not changed: the order and spacing of handles.
