buds rename + applet-list shell — Buddies → Buds everywhere (model field, slug, URL, view, DOM, CSS); my_buds.html + my_posts.html share new _applet-list-shell.html partial — vertical-title applet-scroll card; my_posts hosts two side-by-side in landscape, stacked in portrait — TDD

- lyric/0005 RemoveField+AddField (RenameField doesn't rename the implicit M2M through table; field was new in 0004 so no data loss). Lyric.User.buddies → User.buds; related_name added_as_buddy → added_as_bud.
  - applets/0007 renames Applet slug my-buddies → my-buds + name 'My Buddies' → 'My Buds'. UI rationale: BILLBUDDIES overflowed the page-header band; in-game term collapses to BILLBUDS.
  - billboard/0006 alter Line.Meta.ordering = ('created_at', 'id') — was already in models.py, just generates the corresponding migration (formalizing the ordering decision from the May-8b refactor).
  - global rename via sed: buddies → buds, buddy → bud across 16 files (templates, SCSS, JS, ITs, FTs, page object, view code). 4 file renames via git mv: my_buddies.html → my_buds.html, _applet-my-buddies.html → _applet-my-buds.html, _buddy_panel.html → _bud_panel.html, _buddy_add_panel.html → _bud_add_panel.html, _buddy.scss → _bud.scss. Test files renamed too: test_buddies.py → test_buds.py, test_my_buddies.py → test_my_buds.py, test_buddy_btn.py → test_bud_btn.py. core.scss @import 'buddy' → 'bud'.
  - new shared partial templates/apps/applets/_partials/_applet-list-shell.html — vertical-rotated <h2> + scrollable <ul> aperture, parameterised via {% include %} so a single page can invoke it more than once. Params: shell_title, shell_items, shell_item_template, shell_list_id, shell_empty.
  - my_buds.html: single shell invocation w. add-bud panel below (page_class page-billbuds).
  - my_posts.html: two shell invocations (own posts + posts shared with me) inside .applet-list-page--two-up — portrait stacks them; landscape lays side-by-side via @media (orientation: landscape) flex-direction: row (page_class page-billposts).
  - SCSS: drop the bottom-anchored .buds-page block; new shared .applet-list-page (extends %billboard-page-base, flex-column + padding) w. .applet-scroll inside (extends %applet-box) and .applet-list inside that (flex: 1, overflow-y: auto). .applet-list-page--two-up flips to row layout in landscape. Body class trio gains page-billposts.
  - 841 ITs + 5 my_buds/my_posts FTs green.
