Always copy share-page links and remove profile copy formats

[FlintSH]

Upload profiles could make Copy link return Markdown, HTML, raw-file URLs, or download URLs. Copy actions now consistently return the plain share-page URL across web uploads, pastes, bulk actions, notifications, and generated screenshot tools.

Remove the profile's Copy format selector and preset setting. The upload API always returns the share-page URL in url, pageUrl, and the legacy copyText alias, so previously downloaded uploader configurations keep working. Ignore retired copyFormat values in saved profiles, imported recipes, requests, and in-progress chunk snapshots; all other profile preferences and validation remain in place.

Expected UI changes: the profile editor no longer has a Copy format selector, and the Public screenshots starter describes its minimal share page and random filenames. Paste share-link fields show plain share-page URLs.

Fixes #213.

Validation:

• 375 unit tests passed.
• 20 database integration tests passed against a fresh disposable PostgreSQL database, including legacy Markdown/HTML/raw/download profiles through multipart and both chunk-completion APIs, plus profile listing/export/import.
• 42 browser checks passed with real clipboard readback and mocked upload responses, covering individual/bulk actions, notifications, paste fields, old response formats, and the removed profile control. Desktop/mobile screenshots reviewed; no browser errors.
• TypeScript, ESLint on changed files, Prettier, and diff checks passed.

Greptile Summary

• Standardized upload responses so current and legacy clients receive the encoded share-page URL in url, pageUrl, and copyText.
• Retired copy-format persistence while continuing to accept legacy profile, recipe, request, and in-progress chunk values.
• Updated generated uploader configurations and dashboard copy actions to use plain share-page URLs.
• Added Settings and Profile bookmark aliases that preserve query parameters and open the intended current preference card.

Confidence Score: 5/5

Safe to merge; the changed upload-link compatibility and preference-navigation behavior completed successfully.

No issues were found. Focused upload endpoint checks confirmed legacy copy-format inputs produce the intended normalized links, and rendered navigation checks confirmed legacy bookmarks select and reveal the intended current settings.

Files Needing Attention: None.

T-Rex Logs

What T-Rex did

• Authored and ran the upload API compatibility test script, and compared its before/after outputs against base revision and PR HEAD.
• Verified that the PR head check returns HTTP 200 for legacy copyFormat and clarified that the share-page URL components url, pageUrl, and copyText align, while rawUrl and downloadUrl stay distinct.
• Authored and executed the render navigation proof workflow, including the Chromium navigation script and the navigation proof command script.
• Observed the render navigation proof results, including the output showing 21 passing tests.
• Captured before/after render recordings to document navigation behavior changes for legacy bookmarks.
