Pull request overview

Updates GreptimeDB documentation to reflect the InfluxDB line protocol “append mode” behavior and how HTTP hints affect auto-created tables, including the interaction between append_mode and merge_mode.

Changes:

• Documented per-header HTTP hint format (x-greptime-hint-<key>) in the HTTP API docs (EN/ZH).
• Added/updated InfluxDB line protocol docs to explain how explicitly setting append_mode=true impacts auto-created tables (EN/ZH).
• Refined the performance-tuning guidance around merge modes vs append-only behavior (EN/ZH).

• The list formatting breaks at the “In InfluxDB…” bullet: the continuation lines for the GreptimeDB explanation aren’t indented, so they render as a separate paragraph instead of part of the same list item. Indent the continuation lines under the bullet to keep the list structure consistent.

- In InfluxDB, a point represents a single data record with a measurement, tag set, field set, and a timestamp.
In GreptimeDB, it is represented as a row of data in the time-series table,
where the table name aligns with the measurement,
and the columns are divided into three types: Tag, Field, and Timestamp.
