Add analytics tracking to wordpress-rs post list and settings

[nbradbury]

Description

Adds analytics tracking to the wordpress-rs post list (PostRsListViewModel) and post settings (PostRsSettingsViewModel) to achieve parity with the legacy implementations.

Post list events (PostRsListViewModel):

• POST_LIST_TAB_CHANGED — when the user swipes or taps a tab
• POST_LIST_CREATE_POST_TAPPED — when the FAB is tapped
• POST_LIST_SEARCH_ACCESSED — when search mode is opened
• POST_LIST_AUTHOR_FILTER_CHANGED — when the author filter changes
• POST_LIST_ITEM_SELECTED — when a post is tapped to edit
• POST_LIST_BUTTON_PRESSED — when a post menu action is tapped

Post settings events (PostRsSettingsViewModel):

• EDITOR_POST_VISIBILITY_CHANGED, EDITOR_POST_PASSWORD_CHANGED, EDITOR_POST_SCHEDULE_CHANGED, EDITOR_POST_CATEGORIES_ADDED, EDITOR_POST_TAGS_CHANGED — via trackPostSettings() (adds via=settings)
• EDITOR_POST_SLUG_CHANGED, EDITOR_POST_EXCERPT_CHANGED, EDITOR_POST_FORMAT_CHANGED — via direct track()

All settings events only fire when the value actually changes, matching legacy behavior.
