feat(ios): update for 4.16.3

[dcrawbuck]

Summary

• 4.16.2 -> 4.16.3
• Upstream diff: superwall/Superwall-iOS@4.16.2...4.16.3
• Upstream changelog source: CHANGELOG.md @ 4.16.3 — "Fixes a build error when compiling the SDK with Xcode 26.0."

This is a small patch release containing a single fix (an ambiguous CGFloat/Double arithmetic call that failed to compile under Xcode 26.0) plus the corresponding version bumps in Constants.swift and SuperwallKit.podspec. No public API or behavior changes.

Checklist of doc updates performed

• content/docs/ios/index.mdx — bumped <SdkLatestVersion version="..."> to 4.16.3
• content/docs/ios/sdk-reference/index.mdx — bumped <SdkLatestVersion version="..."> to 4.16.3
• content/docs/ios/changelog.mdx — added ## 4.16.3 entry verbatim from upstream changelog, above the existing ## 4.16.2 entry (history preserved, nothing removed)
• Verified content/docs/ios/quickstart/install.mdx — SPM/CocoaPods snippets use major-version range pins (4.0.0 lower bound / < 5.0.0), not exact patch pins, so no change needed
• Verified content/docs/ios/sdk-reference/getDeviceAttributes.mdx — contains "available in version 4.16.2+" feature-introduction markers for fontScale/fontSize/preferredContentSizeCategory; left unchanged since those features were introduced in 4.16.2, not 4.16.3
• Confirmed no other stale 4.16.2 references remain in content/docs/ios/ outside the preserved changelog history section

Verification

• bun test — 64 pass / 0 fail
• bun run build:cf — could not complete in this sandbox (OOM-killed, exit 137, during Vite's production chunk-rendering step across the site's ~7425 modules on a 3.8GB-RAM/2-CPU box). This is an environment resource constraint unrelated to the 3-line content diff in this PR — reproduced the same OOM kill on a bare vite build with a reduced memory ceiling. Recommend re-running bun run build:cf in CI/on a larger box before merge.

Follow-ups / known gaps

• bun run build:cf should be re-verified in an environment with more available memory before merging, since it could not be completed here.

Note

Low Risk
Documentation-only version bump and changelog text; no runtime or API changes in this repo.

Overview
Updates iOS docs for SuperwallKit 4.16.3, a patch release whose only user-facing note is fixing an SDK build failure on Xcode 26.0.

Adds a ## 4.16.3 section at the top of changelog.mdx with that fix. Bumps SdkLatestVersion from 4.16.2 to 4.16.3 on the iOS welcome page and SDK reference overview. No install snippets or feature docs were changed.
