feat: add company_templates_folder setting

[C-Bjorn]

Summary

Adds a new optional company_templates_folder setting that allows organisations (or any user running a shared/managed vault) to maintain a second template folder whose contents take priority over the personal templates_folder.

When the setting is empty (default) Templater behaves exactly as before — fully opt-in, zero behaviour change for existing users.

What this adds

src/settings/Settings.ts

• company_templates_folder: string added to the Settings interface and DEFAULT_SETTINGS (default "")
• New add_company_template_folder_setting() UI method — single folder input with FolderSuggest autocomplete, displayed immediately below the existing "Template folder location" setting
  • Label: "Company templates folder (MegaMem)"
  • Helper: "Templates here take priority over your personal templates folder."

src/core/Templater.ts

• New instance method resolve_template_tfile(template_str: string): TFile
  • When company_templates_folder is set, extracts the basename of the requested template and looks for a matching file in the company folder first (handles both Name.md and bare Name references)
  • Falls back to the existing resolve_tfile() behaviour when the company folder is empty or no match is found
• on_file_creation() updated to call templater.resolve_template_tfile() instead of bare resolve_tfile() for both folder template and file regex template resolution — ensures the company folder wins on name collision at runtime
• Auto-exclusion guard added — company_templates_folder is now automatically skipped in on_file_creation(), exactly as templates_folder is. Files created inside the company templates folder will never trigger template processing (no need to also add the folder to the "Ignore folders on file creation" list)

Behaviour

Scenario	Result
company_templates_folder is empty	Identical to stock Templater
Template name exists only in personal folder	Uses personal template (unchanged)
Template name exists only in company folder	Uses company template
Template name exists in both folders	Company template wins
New file created inside company_templates_folder	Skipped — same auto-exclusion as templates_folder

Testing

• Built clean with pnpm run build (334.7 kb)
• Verified in Obsidian: setting appears below "Template folder location", company templates resolve correctly, personal-only templates continue to work, empty setting leaves behaviour unchanged, files created in the company templates folder are not processed
