docs: couple of bugs + style pass on affected pages

[jabbacakes]

Purpose of this PR

Addressing a couple of doc feedback tickets we got from users, plus a style pass on the affected pages. Changes specific to the bug fixes are as follows:

• DOCMP-1732: object-spawning.md updates to samples so that they compile. Some of these were casing errors (that I think I might have introduced a while ago 🙈), adding using to samples so they compile if directly copied and pasted, and other minor tweaks. Ctrl+f for ``` codeblock fencing for a quick review of these changes.
• DOCMP-1728: networktime-ticks.md changes on lines 9 and 13 to clarify LocalTime behaviour. The updates to NetworkTimeSystem.cs are matching updates in the API docs.

💡 Harness Review

The timing correction and updated API references align with the implementation, but the revised spawning guidance still misstates object lifecycle behavior.
