User page: hash-routed view, full block hash, aligned rewards

The per-user view was an overlay modal, but users asked for an
actual page — focused, scrollable, addressable. Replace the modal
with a hash-routed page: selectUser(addr) sets window.location.hash
to #/user/<addr> and a hashchange listener syncs the selection
state back, so browser back/forward and direct-link refresh all
work without a routing library. App renders the dashboard or the
UserDetailPage based on selection.user.

Make the clickable BTC addresses in the Miners table obviously
interactive: accent colour, always-on dashed underline, brighter on
hover/focus. The previous styling rendered them as dim static text
with a hover underline, so it wasn't obvious they were links.

BlocksTable: show the full 64-char block hash as a link to
mempool.space (auto-picks testnet4/signet based on snap.chain).
word-break: break-all keeps the hash from blowing out the column
width. Reward column is split into a tabular-num number span and a
dim 0.75em "BTC" unit span, matching the Block reward tile in the
overview, so numbers line up cleanly across rows.
