style alignment pass, proofs & edits

[m4sterbunny]

Description

IMPORTANT: Need to confirm that /embedded-wallets/dashboard/advanced/custom-chains/ was accidentally excluded from sidebar

• Applies same proofing decisions as made on previous passes over single folders, eg:
  • casing, stops for numbered lists, sentence casing for headings and bolded lists, stops for table descriptions
  • corrected use of code ticks for items that are not parameters (bolding applied)
  • retired > in favor of admonitions

Issue(s) fixed

Fixes #2483

Note

Low Risk
Documentation-only edits (formatting/wording/admonitions) with no code or API changes; main risk is minor doc rendering or navigation/label regressions.

Overview
Applies a repo-wide documentation proofing/style alignment pass across the Embedded Wallets docs: standardizes page titles/sidebar labels, heading sentence casing, list/table punctuation, and replaces inline -> callouts with consistent admonitions (for example, :::tip/:::note).

Also makes small clarity edits (for example, “Dashboard” → “dashboard”, wording tweaks, and a few corrected phrases/links) and adds “Next steps” sections to some auth login pages; no SDK/API behavior changes.

Overall looks good, just not sure about the Katex change. Also only one image was changed for whitespace, not all, we should be consistent in our images particularly.

@yashovardhan weird Katex change was to please bot, have reverted to item on main and this time bot is not moaning about it!
WRT image updated for whitespace -- this was the worse offender by far. Do you want issue opened to address all UI images in the same way we had one dedicated to just tutorials?
