refactor: remove tree dependency from TagsService and PropertiesService

[perber]

Both services only used tree for their IndexAllPages bootstrap — no runtime dependency. IndexAllPages is removed from both services; wiki.go now runs a single parallel GetPages pass at startup that feeds both indexes instead of two sequential ReadPageRaw loops

Pull request overview

This PR refactors tag and property indexing so that TagsService and PropertiesService no longer depend on TreeService for a one-time startup bootstrap. Instead, Wiki performs a single startup walk and batched page load, then feeds raw content into both indexes.

Changes:

• Remove TreeService dependency and IndexAllPages bootstrapping from internal/tags.TagsService and internal/properties.PropertiesService.
• Add Wiki.bootstrapTagsAndProperties() to bootstrap both indexes from a single WalkNodes + parallel GetPages pass.
• Update tests and pagesave side-effect tests to construct services without a tree dependency.
