fix(extension): show Add-to-FC button on subscribed Patreon creators (#1485)

Symptom (operator-flagged): the extension injected the Add-as-source button on a Patreon creator you had NOT subscribed to, but it disappeared once you were subscribed — the opposite of when it's useful. Root cause (extension logic, not Patreon security): Patreon serves a creator under three URL shapes — bare patreon.com/Atole, patreon.com/c/Atole, and patreon.com/cw/Atole (the 'creator workspace' URL you land on once subscribed; documented in patreon_resolver._VANITY_RE). The button's artist-page gate (PLATFORM_ARTIST_PATTERNS.patreon in platforms.js) and its byte-mirror probe pattern (_PLATFORM_PATTERNS in extension_service._derive) only matched the bare single-segment form and explicitly excluded c/. So the subscribed-view URL failed the gate → no button. The ingestion resolver already handled all three; only these two gates were too narrow. Fix: both regexes now accept optional cw/ and c/ prefixes and drop the strict single-segment end-anchor, so a creator's inner page (/cw/Atole/posts, /Atole/membership) also matches — robust to whatever exact shape the subscribed view uses. Nav-page exclusions (home/search/messages/notifications/library/ settings/posts + post permalinks) preserved. New unit test covers all three prefixes, sub-paths, and nav-page rejection (both regexes validated identically). Bump extension 1.0.7→1.0.8 so a fresh signed XPI ships the fix (also exercises batch-5 web-ext-10's AMO sign path end-to-end on the main build).
