fix: send correct time unit when writing Points

[NguyenHoangSon96]

Closes #382

Proposed Changes

• When writing Points, precision in query parameters always set to nanosecond because time in Points always converted into nanoseconds by default.
• Update test cases to respect the new changes above.

Checklist

• CHANGELOG.md updated
• Rebased/mergeable
• A test has been added if appropriate

Pull request overview

This PR addresses a write precision mismatch when writing Point objects to InfluxDB v3: the line protocol payload is serialized with nanosecond timestamps, so the request’s precision query parameter must match to avoid server-side “timestamp out of range for precision” errors (issue #382).

Changes:

• Force precision=nanosecond in write query parameters when writing Point instances.
• Update unit tests to expect precision=nanosecond for Point writes even when client config sets another precision.
• Add an end-to-end integration test covering writing points with timestamps provided in different input units.

I think we should tweak javadoc for precision args just a tiny bit, Copilot finding makes sense. And cover the logic more by unit test in addition to e2e test.

sorry found one last occurrence, otherwise this PR is GTG
