feat: add CocoaPods podspec support for all kit tracks

[nickolas-dimitrakas]

Background

• Restores CocoaPods .podspec files for all 28 active kit tracks in the monorepo, each independently installable by track name (e.g. mParticle-Braze-12). Exceptions: Rokt (mParticle-Rokt) and OneTrust (mParticle-OneTrust) retain their existing pod names.

What Has Changed

• Added 25 new podspecs and updated 3 existing ones (apptentive-6, localytics-6, localytics-7)
• All podspecs: source set to monorepo URL, monorepo-relative source_files paths, core SDK dependency pinned to ~> 9.0, versions restored from last published mparticle-integrations releases
• release-draft.yml: added consolidated step to bump s.version across all podspecs on release

Checklist

• I have performed a self-review of my own code.
• I have made corresponding changes to the documentation.
• I have added tests that prove my fix is effective or that my feature works.
• I have tested this locally.

Additional Notes

• No updates have been made to push to cocoapods, this process is manual
