docs: fix what no longer matches lazysecrets, and say each thing once (#74)

Fixes:
- A newer release shows in the status pane (`↑ v0.2.0`), not the footer.
- The account in `lazysecrets list` is plain `Azure` with one az account; `Azure:<user>/<tenant>` only with several.
- Sharing lists subscription, workspace and scope links, and opening takes Azure portal links.
- `--timeout` and `--clipboard-clear` are documented, next to their config keys.
- `--kind`'s description reads, and says `vault` covers scopes and repo files.
- `lazysecrets -h` lists `list`'s `--stars`, `--notes`, `--recent` and `--expiry`.
- README typos; "Supported platforms" is "Sources".

Trimmed:
- An option is documented on its topic's page; config.md's example keeps the general ones and links the rest.
- The fzf picker lives in docs/integration.md; the README keeps a link and the screenshot.
- The clipboard clear, reveal timeout, per-account stars, Azure's "no extra requests" and `open --action` are each said once.
- The status pane's contents are a list; build sizes and PR-title spellings are gone from development.md.
